Biz Markie x I Love Tune-Up. There is a new king of commercials in hip-hop these days and he’s literally all about the Biz. The iTunes music organizing software company has enlisted Biz Markie and Andy Milonakis of all people for their first major ad campaign. We like seeing artists like Biz Markie re-invent themselves to stay relevant in today’s pop culture. Now you can’t go anywhere without hearing “Just a Friend” including the recent Radio Shack ad and last year’s big Heineken ad success. Via: TRU
