A greatest hits album (sometimes referred to as a "best of" album) is a compilation album of successful, previously released songs by a particular music artist or band. To increase the appeal of the album – especially to people who already own the previously released material – it is common to include remixes of popular songs or new material, with new songs often being released as singles (and themselves sometimes becoming successful).
Greatest Hits is a double disc greatest hits album for the late rapper 2 Pac, released by Death Row Records in 1998. The album's nonchronological sequence highlights 2 Pac's music; the 21 popular hits, some slightly re-edited for legal reasons, are accompanied by four previously unreleased songs: "God Bless the Dead" (Dedicated to a "Biggie Smalls", thought by many to be about the late Notorious B.I.G.), "Unconditional Love", "Troublesome '96", and "Changes" which has since become one of Shakur's best known songs.
Greatest Hits (also known as Alice in Chains Greatest Hits) is a greatest hits collection for the grunge band Alice in Chains. It was released on July 24, 2001 on Columbia Records. It is the second collection of hit songs by the band, shorter than the previous release, Nothing Safe: The Best Of The Box.
