Dr. Dre is back online with the relaunch of his official website and the release of Detox's new single, "I Need a Doctor."

Well, the song isn't quite out yet but you can now stream the final/official version of the new Eminem and Skylar Grey-featured single right now. The song—which was leaked back in November in unfinished form—will hit iTunes on Tuesday (February 1).

The pair shot the music video for the song in Los Angeles earlier this month. Still no word on when the clip will arrive but it should be something dope.
