Eminem and Dr. DreA lot has happened in the dozen years since Dr. Dre released a solo album. A lot. Dre's much-storied third album, 'Detox,' is kinda like hip-hop's own 'Chinese Democracy.' Except that everyone expects great things from this one. It's almost time to finally cash in those chips for the money and the big payoff: After years of hearing Dre's collaborators -- including Snoop Dogg and Ice Cube -- discuss their contributions and speculate about the album's release, 'Detox' finally drops in April. For real, this time.

While certain unfinished tracks were leaked in the past -- much to Dre's chagrin -- when an unmastered version of the song 'Kush' leaked last fall, he quickly mastered it and released it officially via iTunes. Then came a video. So, whereas previous leaked tracks were allegedly removed from the album's final tracklist, 'Kush' was the forced first single.

Last November, just one week after 'Kush' was released, producer Alex da Kid said the track he worked on called 'I Need a Doctor' (feat. Eminem and Skylar Grey) would be the official second single from 'Detox.' Turns out, the kid was right. Watch the video after the jump.
