"S.D.S." stands for "Somebody Do Somethin'." So what has the second-best-known rapper from rapper done here? For starters, he's channeling his inner superhero. But the bigger picture is that he's not rapping about money, cars, and clothes (as far as I can tell). It's too early to say if this is a new direction for Mac or just a temporary detour. However, it is NOT the average conceptual hip-hop video, and that alone makes this clickworthy.
