The rap mogul netted $37 million last year, placing him at the top of Forbes' Hip Hop Cash Kings list for the fourth time in the last five years.

Not far behind was Diddy, who earned a reported $35 million. Jay's partner on "Watch the Throne," Kanye West, earned $16 million.
If all goes well with "Watch the Throne," Jay and Kanye will be adding lots more to their coffers.
