Discography: The Complete Singles Collection is an 18 track compilation by the UK electronic music group Pet Shop Boys. It was first released in 1991. The album charted at No 3 in the UK album charts. As the name suggests, Discography is a collection of all of the hit singles by Pet Shop Boys up to that point (1991), alongside two new tracks "DJ Culture" and "Was It Worth It?". Although all other songs on this album had appeared in some form on their previous albums, only six of the songs previously appeared on an album in their single versions. Read more on Last.fm.
