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.

A jukebox musical is a stage or film musical that uses previously released popular songs as its musical score.

Calamity Jane (A Musical Western) is a stage musical based on the historical figure of frontierswoman Calamity Jane.

 According to Jodie Prenger, star of the "Calamity Jane" 2014 - 15 UK tour, the songs added for the stage musical had been written for but not included in the "Calamity Jane" movie ("Love You Dearly" had been used in the 1954 Doris Day musical film "Lucky Me").
