Musicians (and athletes, too, for that matter) aren't too great at sticking to their retirement plans. This is particularly true in hip-hop, where the latest culprit is Houston's Scarface. After a long run both on his own and as a member of the Geto Boys, he "called it quits" following 2008's solid Emeritus. Of course, though, he would announce two years later that he was returning to music to release his first mixtape, Dopeman Music, and comeback LP, The Habit. Details remain skim at this point, but it's been announced that Eminem will provide beats for the project.
