15. Kasseem “Swizz Beatz” Dean, $6.5 million (tie)
It’s been more than a decade since Swizz burst onto the scene by producing DMX’s “Ruff Ryders’ Anthem” at age 16; since then, he’s added hundreds of credits to his catalog, most recently on Jay-Z and Kanye West’s Watch The Throne. He tied the knot with singer Alicia Keys last summer and recently announced a lucrative partnership with Reebok.
