It’s been 15 years since his murder, but Tupac’s legacy continues on. Just weeks after his 40th birthday anniversary, which featured a performance of Meek Mill and Rick Ross’s “Tupac Back,” the late Shakur gets another victory, with his Greatest Hits album reaching Diamond status on the Billboard charts.

Earlier this June, the RIAA announced that the two-disc collection sold another million copies, pushing its total sales since its 1998 release to 10 million. The album has ultimately edged-out ’96s All Eyez on Me to become Shakur’s biggest selling album and marks his first time reaching Diamond status in his career.

Greatest Hits is noted for featuring four previously unreleased tracks from the legendary rapper and a number of re-edited versions of previously released songs. The album’s single “Changes” also helped earn Pac the first and only posthumous Grammy Award nomination since for Best Rap Solo Performance.

The song “God Bless the Dead” is particularly well known for a lyric in Pac says, “Rest in peace to my motherfucker Biggy Smallz.” While many misinterpreted to be a reference to former foe Notorious B.I.G., who passed after Pac’s death, the lyric was actually a reference to an assoicate of Stretch of the Live Squad, who was featured on the very song.
