2 Pacs Greatest Hits is a double-disc greatest hits album for late American rapper 2Pac, released by Amaru/Death Row/Interscope Records/Jive in 1998.The album's non-chronological sequence highlights 2Pac's career; the 21 popular hits, some slightly re-edited for legal reasons, are accompanied by four previously unreleased songs: the dead friends tribute "God Bless the Dead", the dedication song "Unconditional Love", the tough talk "Troublesome '96", and the album's single "Changes" also helped earn 2Pac the first and only posthumous Grammy Award nomination since for Best Rap Solo Performance. Some tracks have alternate mixes, while the original mix of "California Love" makes its first proper album appearance after only being available as a single prior.
This is one of 2Pac's two albums—and one of only nine hip hop albums—to have been certified Diamond in the United States as stated via Wiki.
