The Dance Club Songs chart is a weekly chart published exclusively by Billboard in the United States. It is a national survey of the songs which are the most popular in nightclubs across the country and is compiled from reports from a national sample of disc jockeys. It was launched as the Disco Action Top 30 chart on August 28, 1976, and became the first chart by Billboard to document the popularity of dance music. Since its inception, several artists have set various records and garnered multiple achievements. In January 2017, Billboard proclaimed Madonna as the most successful artist in the history of the chart, ranking her first in their list of the 100 top all time dance artists and Janet Jackson being the second most successful dance club artist of all-time; Madonna also holds the record for the most number-one songs, with 50. Katy Perry holds the record for having eighteen consecutive number-one songs. Perry's third studio album, Teenage Dream (2010), became the first album in the history of the chart to produce at least seven number-one songs by a lead artist between 2010–2012, a record it held solely until Rihanna's eighth studio album Anti produced eight chart toppers through 2016-2017. Rihanna is the only artist to have achieved five number-one songs in a calendar year.
Hot Rock & Alternative Songs is a record chart published by Billboard magazine. From its debut on June 20, 2009, through October 13, 2012, the chart ranked the airplay of songs across alternative, mainstream rock, and triple A radio stations in the United States. Beginning with the chart dated October 20, 2012, the chart has followed the methodology of the Billboard Hot 100 by incorporating digital download sales, streaming data, and radio airplay of rock songs over all formats. From that time until mid-2020, only the performance of core rock songs, including those with an "alternative bent", were tabulated and ranked for the chart. With the chart dated June 13, 2020, Billboard revamped the chart to permit a broader selection of songs considered alternative "hybrids" with other genres and renamed it to Hot Rock & Alternative Songs.
