On Me Against the World, the 1995 album from Tupac Shakur, the prodigious rapper foretells his death. "I'm having visions of leaving here in a hearse/ God can ya feel me?/ Take me away from all the pressure/ and all the pain/ show me some happiness again," he raps on "So Many Tears." Eighteen months later, while riding in the passenger seat under the iridescent glow of the Las Vegas strip with Marion "Suge" Knight at the wheel, Tupac was gunned down and mortally wounded. Or was he?
