By 2009, In This Skin had sold 2.9 million copies in the US and produced four singles. In 2004, Simpson released her fourth studio and her first Christmas album, Rejoyce: The Christmas Album.

The discography of Weezer, an American rock band, consists of 15 studio albums, two compilation albums, one video album, nine extended plays, 37 singles and 40 music videos. Weezer's self-titled debut studio album, often referred to as The Blue Album, was released in May 1994 through DGC Records. The album was a commercial success, peaking at number 16 on the US Billboard 200 and spawning the singles "Undone – The Sweater Song" and "Buddy Holly", both of which were responsible for launching Weezer into mainstream success with the aid of music videos directed by Spike Jonze. It has sold 3.3 million copies in the United States and has been certified triple platinum by the Recording Industry Association of America (RIAA), becoming the band's best selling album to date. Following the success of their debut album, Weezer took a break from touring for the Christmas holidays. Lead singer Rivers Cuomo began piecing together demo material for Weezer's second studio album. Cuomo's original concept for the album was a space-themed rock opera, Songs from the Black Hole. Ultimately, the Songs from the Black Hole album concept was dropped; the band, however, continued to utilize songs from these sessions into work for their second studio album. Pinkerton was released as the band's second studio album in September 1996. Peaking at number 19 on the Billboard 200, it was considered a critical and commercial failure at the time of its release, selling far less than its triple platinum predecessor. However, in the years following its release, it has seen much critical and commercial championing.
