A CD single (sometimes abbreviated to CDS) is a music single in the form of a compact disc. The standard in the Red Book for the term CD single is an 8 cm (3-inch) CD (or Mini CD).  It now refers to any single recorded onto a CD of any size, particularly the CD5, or 5-inch CD single. The format was introduced in the mid-1980s but did not gain its place in the market until the early 1990s. With the rise in digital downloads in the early 2010s, sales of CD singles have decreased.
Commercially released CD singles can vary in length from two songs (an A side and B side, in the tradition of 7-inch 45-rpm records) up to six songs like an EP. Some contain multiple mixes of one or more songs (known as remixes), in the tradition of 12-inch vinyl singles, and in some cases, they may also contain a music video for the single itself (this is an enhanced CD) as well as occasionally a poster. Depending on the nation, there may be limits on the number of songs and total length for sales to count in singles charts.
CD singles were first made eligible for the UK Singles Chart in 1987, and the first number 1 available on the format in that country was "I Wanna Dance with Somebody (Who Loves Me)" by Whitney Houston in May 1987. 
The Mini CD single CD3 format was originally created for use for singles in the late 1980s, but met with limited success, particularly in the US.  The smaller CDs were more successful in Japan  and had a resurgence in Europe early this century, marketed as "Pock it" CDs, being small enough to fit in a shirt pocket. By 1989, the CD3 was in decline in the US (replaced by the 5-inch CD single, called CD-5). 
It was common in the 1990s for US record companies to release both a two-track CD and a multi-track (usually "remix") maxi CD. In the UK, record companies would also release two CDs but, usually, these consisted of three tracks or more each.
During the 1990s, CD single releases became less common in certain countries and were often released in smaller editions, as the major record labels feared they were cannibalizing the sales of higher-profit-margin CD albums. Pressure from record labels made singles charts in some countries become song charts, allowing album cuts to chart based only on airplay, without a single ever being released. In the US, the Billboard Hot 100 made this change in December 1998, after which very few songs were released in the CD single format in the US, but they remained extremely popular in the UK and other countries, where charts were still based solely on single sales and not radio airplay. At the end of the 1990s, the CD was the biggest-selling single format in the UK, but in the US, the dominant single format was airplay. With the advent of digital music sales, the CD single has largely been replaced as a distribution format in most countries, and most charts now include digital download counts as well as physical single sales.
In Australia, the Herald Sun reported the CD single is "set to become extinct". In early July 2009, leading music store JB Hi-Fi ceased stocking CD singles because of declining sales, with copies of the week's No. 1 single often selling as few as only 350 copies across all their stores nationwide.  While CD singles no longer maintain their own section of the store, copies are still distributed but placed with the artist's albums. That is predominantly the case for popular Australian artists such as Jessica Mauboy, Kylie Minogue and, most recently, Delta Goodrem, whose then-recent singles ("What Happened to Us", "Put Your Hands Up (If You Feel Love)" and "Sitting on Top of the World" respectively) were released on CD in limited quantities. The ARIA Singles Chart is now "predominantly compiled from legal downloads", and ARIA also stopped compiling their physical singles sales chart. "On a Mission" by Gabriella Cilmi was the last CD single to be stocked in Kmart, Target and Big W, who then concluded stocking newly released singles. Sanity Entertainment, having resisted the decline for longer than the other major outlets, has also ceased selling CD singles.
In Germany, CD singles continue to be regularly issued by all major and some minor labels, and both of domestic and foreign artists.
In China and South Korea, CD single releases have been rare ever since the format was introduced, due of the amount of infringement and illegal file sharing over the internet, and most of the time singles have generally been album cuts chart based only on airplay, but with the advent of digital music the charts have also occasionally included digital download counts.[ citation needed ]
In Greece and Cyprus, the term "CD single" is used to describe an extended play (EP) in which there may be anywhere from three to six different tracks. These releases charted on the Greek Singles Chart (before it abandoned tracking altogether) with songs released as singles.

The original CD single (sometimes mini CD single or 3-inch CD or CD3 in the US) is a music single released on a mini Compact Disc that measures 8 cm (3.1 in) in diameter, rather than the standard 12 cm (4.7 in). They are manufactured using the same methods as standard full-size CDs, and can be played in most standard audio CD players and CD-ROM disc drives. 
The format was first released in the United States, United Kingdom, Japan, France, West Germany, and Hong Kong in 1987 as the replacement for the 7-inch single.  While mini CDs quickly fell out of popularity among most major record labels (partly due to their incompatibility with many slot-loading CD players), they lasted longer as a popular, low cost way for independent musicians and groups to release music. 
Capable of holding up to 20 minutes of music, most mini CD singles contain at least two tracks, often consisting of a single edit and an instrumental version in the same way as 7-inch vinyl singles. 
These were released in both a 5-inch size slim jewel case and long flip-out sleeve snap-packs. These sleeves could be 'snapped' and folded into a small 3-inch (8-cm) square, rather than the original 6 by 3 inches (15 cm × 8 cm) length when originally sold.
Beginning in 1999 some labels began to package mini CDs in 12 cm slimline cases. As the "tanzaku" sleeves slowly morphed into the use of slimline jewel cases, the mini CD single was haulted from production in the early 2000s.
As popularity diminished, one of the last Japanese 8 cm CD single released was a reissue and repackaging of "I Was Born to Love You" by Queen in 2004. Many of the artists who released 3-inch CDs are from that era, including Wink, Madonna, Phil Collins, Michael Jackson, Queen, U2, Prince, Metallica, Bros, Huey Lewis and the News, Bon Jovi, Kylie Minogue, Falco and George Michael. Some singles packaged in 5inch single jewel cases contained a 5-inch CD adapter.
Most were sold at around ¥1,000 (£6 or $9) at the time of release during the late 1980s, early 2000s to the present day.
However, there has been a small revival in the mini CD single with Japanese artists such as Hibari Misora with a reissue of her 1989 single "Kawa no Nagare no Yoni" in May 2019 in original long "tanzaku" form, by the record company Nippon Columbia. 
US versions were often packaged in cardboard slipcases, either 3-inch square or 6-inch by 3-inch gatefold. Others were released in 5-inch slimline single cases, which allowed an adapter to be included with the CD. At the time of first release in 1987, their retail price was between $4 and $6, at least $3 less than even the least-expensive 5-inch discs. Delos Records, a small, independent label, issued the first commercially available 3-inch CDs in 1987 with 20 classical and jazz titles. The Massachusetts-based Rykodisc issued Frank Zappa's “Peaches en Regalia” the first pop 3-inch CD. Initially when released, 300,000 of the discs were shipped to retail outlets.  Noted oldies label Rhino had a series of over 60 3-inch CDs released throughout 1988 entitled "Lil' Bit Of Gold".[ citation needed ]
In the United Kingdom, 3-inch CDs were made mostly in a small square case/cover form only, some including a 5-inch CD adapter to use in normal compact disc players. Although the format was not widely available in the United Kingdom, several artists have released singles in the format.
From a technical standpoint, a 3-inch CD follows the Red Book standard for CD digital audio. The major difference is that the smaller physical size of the disc allows for fewer data sectors, meaning the disc can store less audio. The majority of audio CD players and CD-ROM drives have a smaller circular indentation in the CD tray for holding these discs. Most slot-loading drives, such as those found in some car CD players, are unable to manipulate the smaller discs or their adapters. Laptop drives generally only require the centre hole to hold the disc so the smaller diameter is irrelevant. In fact, software and drivers for some hardware are provided on the 3-inch discs.
In the United States and United Kingdom, the format barely lasted into the early 1990s, partly due to inconvenience of needing to attach an adapter on every disc (very few packages were issued with one) before playing. Sony remained in support of the 3-inch CD having had plans to launch a 3-inch CD player for the Japanese market in 1988. 
It was largely replaced by simply putting less music on a regular full-size CD, at least among major labels. The full-size discs are a more standard manufacturing process and so may end up being cheaper to press. The CD single format continued until 2000 for Japanese releases. Despite the unpopularity it survived with publishers adopting the 3-inch CD as an inexpensive way of presenting bonus material with books. 
The slim jewel boxes used for 3-inch CDs are nearly the same size as 3.5-inch floppy disks, making storage boxes for 3.5-inch floppies usable for 3-inch CDs as well.

In September 2003, there was talk of ringtones for mobile phones outstripping CD singles sales for the year 2004. 
Woolworths Group, which previously accounted for one third of all CD sales in the country, stopped selling CD singles in August 2008, citing the "terminal decline" of the format as customers moved to digital downloads as their preferred method of purchasing single tracks   (the Woolworths chain itself would collapse the following November).
In July 2009, The Guardian reported that Florence + The Machine's single 'Rabbit Heart (Raise It Up)' sold a CD and 7inch vinyl combined total of 64 copies, where it reached number 16 in the Mid-Week Chart. 
In March 2011, Mercury Records announced that they were to stop manufacturing CD singles for lack of demand and loss of money on the format in 2010. 
As of 2012, selected HMV stores sold a small selection of CD singles, mostly charity releases and acts from The X Factor .
'Bad Habits' by Ed Sheeran was the best-selling CD single as of September 2021 with 11,000 copies. 
The compact disc (CD) is a digital optical disc data storage format that was co-developed by Philips and Sony to store and play digital audio recordings. In August 1982, the first compact disc was manufactured. It was then released in October 1982 in Japan and branded as Digital Audio Compact Disc.
Digital Audio Tape is a signal recording and playback medium developed by Sony and introduced in 1987. In appearance it is similar to a Compact Cassette, using 3.81 mm / 0.15" magnetic tape enclosed in a protective shell, but is roughly half the size at 73 mm × 54 mm × 10.5 mm. The recording is digital rather than analog. DAT can record at sampling rates equal to, as well as higher and lower than a CD at 16 bits quantization. If a comparable digital source is copied without returning to the analogue domain, then the DAT will produce an exact clone, unlike other digital media such as Digital Compact Cassette or non-Hi-MD MiniDisc, both of which use a lossy data reduction system.
In music, a single is a type of release, typically a song recording of fewer tracks than an LP record or an album. One can be released for sale to the public in a variety of formats. In most cases, a single is a song that is released separately from an album, although it usually also appears on an album. In other cases a recording released as a single may not appear on an album.
An extended play (EP) is a musical recording that contains more tracks than a single but fewer than an album or LP record. Contemporary EPs generally contain four or five tracks, and are considered "less expensive and time-consuming" for an artist to produce than an album. An EP originally referred to specific types of records other than 78 rpm standard play (SP) and LP, but it is now applied to mid-length CDs and downloads as well. In K-pop they are usually referred to as mini albums. Ricardo Baca of The Denver Post said, "EPs—originally extended-play 'single' releases that are shorter than traditional albums—have long been popular with punk and indie bands." In the United Kingdom, the Official Chart Company defines a boundary between EP and album classification at 25 minutes of maximum length and no more than four tracks.
A phonograph record, a vinyl record, or simply a record, is an analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove. The groove usually starts near the periphery and ends near the center of the disc. At first, the discs were commonly made from shellac, with earlier records having a fine abrasive filler mixed in. Starting in the 1940s polyvinyl chloride became common, hence the common use of the word vinyl.
A CD player is an electronic device that plays audio compact discs, which are a digital optical disc data storage format. CD players were first sold to consumers in 1982. CDs typically contain recordings of audio material such as music or audiobooks. CD players may be part of home stereo systems, car audio systems, personal computers, or portable CD players such as CD boomboxes. Most CD players produce an output signal via a headphone jack or RCA jacks. To use a CD player in a home stereo system, the user connects an RCA cable from the RCA jacks to a hi-fi and loudspeakers for listening to music. To listen to music using a CD player with a headphone output jack, the user plugs headphones or earphones into the headphone jack.
A digital music store is a business that sells digital audio files of music recordings over the Internet. Customers gain ownership of a license to use the files, in contrast to a music streaming service, where they listen to recordings without gaining ownership. Customers pay either for each recording or on a subscription basis. Online music stores generally also offer partial streaming previews of songs, with some songs even available for full length listening. They typically show a picture of the album art or of the performer or band for each song. Some online music stores also sell recorded speech files, such as podcasts, and video files of movies.
An album is a collection of audio recordings issued on compact disc (CD), vinyl, audio tape, or another medium such as digital distribution. Albums of recorded sound were developed in the early 20th century as individual 78 rpm records collected in a bound book resembling a photograph album; this format evolved after 1948 into single vinyl long-playing (LP) records played at 33+1⁄3 rpm.
Optical disc packaging is the packaging that accompanies CDs, DVDs, and other formats of optical discs. Most packaging is rigid or semi-rigid and designed to protect the media from scratches and other types of exposure damage.
Mini CDs, or pocket CDs, are CDs with a smaller diameter and one-third the storage capacity of a standard 120 mm disc.
An album cover is the front packaging art of a commercially released studio album or other audio recordings. The term can refer to either the printed paperboard covers typically used to package sets of 10 in (25 cm) and 12 in (30 cm) 78-rpm records, single and sets of 12 in (30 cm) LPs, sets of 45 rpm records, or the front-facing panel of a cassette J-card or CD package, and, increasingly, the primary image accompanying a digital download of the album, or of its individual tracks.
CD Video is a format of optical media disc that was introduced in 1987 that combines the technologies of standard compact disc and LaserDisc. CD-V discs are the same size as a standard 12-cm audio CD, and contain up to 20 minutes' worth of CD audio that can be played on any audio CD player. It also contains up to 5 minutes of LaserDisc video information with digital CD-quality sound, which can be played back on a newer LaserDisc player capable of playing CD-V discs or CD-V-only players.
A maxi single or maxi-single is a music single release with more than the usual two tracks of an A-side song and a B-side song.
A promotional recording, or promo, or plug copy, is an audio or video recording distributed free, usually in order to promote a recording that is or soon will be commercially available. Promos are normally sent directly to broadcasters, such as music radio and television stations, and to tastemakers, such as DJs, music journalists, and critics, in advance of the release of commercial editions, in the hope that airplay, reviews, and other forms of exposure will result and stimulate the public's interest in the commercial release.
The UK Singles Chart is compiled by the Official Charts Company (OCC), on behalf of the British record industry, listing the top-selling singles in the United Kingdom, based upon physical sales, paid-for downloads and streaming. The Official Chart, broadcast on BBC Radio 1 and MTV, is the UK music industry's recognised official measure of singles and albums popularity because it is the most comprehensive research panel of its kind, today surveying over 15,000 retailers and digital services daily, capturing 99.9% of all singles consumed in Britain across the week, and over 98% of albums. To be eligible for the chart, a single is currently defined by the Official Charts Company (OCC) as either a 'single bundle' having no more than four tracks and not lasting longer than 25 minutes or one digital audio track not longer than 15 minutes with a minimum sale price of 40 pence. The rules have changed many times as technology has developed, the most notable being the inclusion of digital downloads in 2005 and streaming in July 2014.
The LP is an analog sound storage medium, a phonograph record format characterized by: a speed of 33+1⁄3 rpm; a 12- or 10-inch diameter; use of the "microgroove" groove specification; and a vinyl composition disk. Introduced by Columbia in 1948, it was soon adopted as a new standard by the entire record industry. Apart from a few relatively minor refinements and the important later addition of stereophonic sound, it remained the standard format for record albums until its gradual replacement from the 1980s to the early 2000s, first by cassettes, then by compact discs, and finally by digital music distribution.
"What's It Gonna Be" is a song performed by British bassline duo H "Two" O and British bassline vocal group Platnum. Digital formats were released to online retailers in the UK on 11 February 2008. Physical formats, including a two-track CD single, a maxi-CD single, and a 12-inch vinyl disc, were released in the UK the same month. The track was licensed by dance label Hard2Beat and peaked at No. 2 on the UK Singles Chart for three weeks.
"Tattva" is a song by British psychedelic rock band Kula Shaker, released as the band's debut single. It was first released in the United Kingdom in 1996 as "Tattva ", then re-issued on 24 June 1996 as a re-recording from their debut album, K (1996), with a different sleeve and track listing. The re-recording reached number four on the UK Singles Chart, number 11 on the Canadian RPM Alternative 30 chart, and number 10 on the US Billboard Modern Rock Tracks chart. In Melody Maker, critic Neil Kulkarni declared "Tattva" and follow-up release "Grateful When You're Dead" to be "the two worst singles of '96".
Record sales or music sales are activities related to selling music recordings through physical record shops or digital music store. Record sales reached the peak in 1999, when 600 million people spent an average of $64 in buying records, bringing a total of $40 billion sales of recorded music. Sales continued declining in the 21st century. The collapse of record sales also made artists rely on touring for most of their income. By 2019, record sales had accounted for less than half of global recorded music revenue, overtaken by streaming. Following the inclusion of streaming into record charts in the mid-2010s, record sales are also referred to as traditional sales or pure sales.
"Dynamite" is a song by Irish pop vocal band Westlife. It was released on 5 July 2019 as the third single from Westlife's eleventh studio album Spectrum. It is their third single released under Universal Music Group and Virgin EMI Records. This is released on band member Shane Filan's fortieth birthday. This is written by Ed Sheeran, Steve Mac and Andrew Wyatt. Their third work released from 2019 and the 2010s decade for the group. Mac also produced the original mix and the Cahill remix of the single, his third one from Spectrum. Midnight Mix of the single were produced by Red Triangle and band member Markus Feehily. This is the second Westlife single Red Triangle co-produced while this is the first single of Westlife to be produced by Feehily and by a Westlife member.
