Yesterday, we got a gang of rap nerds to discuss and dissect Jay-Z and Kanye West's new "H.A.M." single. Some people alleged that Hov took shots at Birdman and Lil Wayne with his "you got baby money" line (re: respective Baby, Weezy F. Baby nicknames), and Forbes agrees. The leading financial publication offers a valuation that puts Jigga's worth at $450 million ("I'm like really half a billi"), along with money-making stats from 2010. Jay pocketed $63 million last year; Wayne took home $20 million; Birdman did not make the Hip-Hop Cash Kings list.
