Snap! is a greatest hits album by The Jam, released in 1983, one year after the group disbanded. The double-album includes all sixteen of the band's UK singles, plus some B-sides, album tracks and rarities. Stephen Thomas Erlewine of Allmusic called it "one of the greatest greatest-hits albums of all time".
Initial quantities of the album included a limited edition 4 track EP, Live, recorded at Wembley Arena during the farewell tour of 1982. Featuring the tracks "Get Yourself Together", "Move On Up", "The Great Depression" and "But I'm Different Now", the EP is notable for the fact that these songs were never re-issued on any other Jam compilation.
In 2006, Universal Music re-released the album in its entirety on CD for the first time, again with initial copies including the limited edition live EP. Prior to this, it had only been available in abbreviated form as the single CD Compact Snap!, which contained only 21 of the 29 tracks from the original double album.
