A greatest hits album, sometimes called a "best of" album or a catalog album, is a compilation of songs by a particular artist or band. Most often the track list contains previously released recordings with a high degree of notability. However, to increase the appeal, especially to people who already own the original release, it is common to include remixes or alternate takes of popular songs; sometimes even new material (previously unreleased) will function as bonus tracks. At times, a greatest hits compilation is the original album release for songs that have themselves been released as a single and charted successfully.
Many of these albums surface despite the unwillingness of original artists to support them, the songwriters being embroiled in fighting record company decisions. Despite The Rolling Stones' conflicts over the control of their tracks, the band-opposed Hot Rocks 1964–1971 surfaced in December 1971, and the contentious legal issues failed to clip the wings of the record's commercial success. Nonetheless, many other of these albums actually receive detailed co-operation from the musicians involved, which can mean trying to present a specific 'goal' or 'sound' in the work (roughly akin to that in concept albums). One example of the latter is the U.S. band Dream Theater's release Greatest Hit (...And 21 Other Pretty Cool Songs), which came out on Rhino Records on April 1, 2008. The tongue-in-cheek title notes how the song "Pull Me Under" has such outsize knowledge compared to the rest of the band's discography.
Madonna's The Immaculate Collection (1990) is the best selling greatest hits compilation by a solo artist; all of the songs on it are presented in different versions than the original hit versions. The Eagles' Their Greatest Hits (1971–1975) (1976) is the best selling greatest hits compilation by a group and also one of the ten best selling albums in history. Greatest hits albums are typically produced after an artist has had enough successful songs to fill out an album release. Some artists, such as David Bowie, Cliff Richard, Mariah Carey, Madonna, Janet Jackson, Britney Spears, Elvis Presley, Michael Jackson, The Beatles, Kenny Rogers, Aerosmith, Kiss, TLC, Dolly Parton, Journey, Los Tigres del Norte, Queen, Kylie Minogue and Billy Joel, have released multiple greatest hits albums through their long careers. Some greatest hits albums are released only at the end of the artist or group's career. For example, My Chemical Romance released a greatest hits album May Death Never Stop You: The Greatest Hits 2001–2013 in 2014 after they disbanded. Other artists, like Eminem have released hits albums in the center of their success. He released Curtain Call: The Hits in 2005 and then Shady XV as a compilation album in 2014.
