MC Hammer joins the fight and takes a swipe at Jay-Z.

MC HAMMER, now going by King Hammer, has dropped a song going at Jay-Z just as he promised. The Oakland veteran took offense to recent Jay-Z bars from Kanye's G.O.O.D. Friday release "So Appalled." The Jiggaman referenced Hammer's money troubles over the years when he said,  "And Hammer went broke so you know I'm more focused / I lost 30 mil so I spent another 30 / 'Cause unlike Hammer 30 million can't hurt me."
