Did you forget about Dre? With a bank balance like that, how could you? Like any good doctor, Dre came up with a successful formula: Become a famous rapper, use your money to open a record label, sign Eminem, and watch the cash keep flowing in.
As part of the group N.W.A, Dre released the seminal album 'Straight Outta Compton', which shocked the general public, broke down barriers, brought rap into the mainstream and made millions of dollars. He broke off from the group to enjoy solo success and opened Death Row Records. Mentoring acts like 50 Cent as well as Eminem, Dre has branched out into other areas, creating a range of high quality headphones which are now recognized as an industry standard. Apple eventually bought the company for $3bn, and Dre entered financial dreamland. After all these years, he's still D.R.E.
