Dr. Dre has been racking up plenty of other financial accomplishments. His latest: capturing this year’s hip-hop cash crown with pretax earnings of $620 million. Not only is that the highest annual total of any entertainer ever evaluated by FORBES, it’s more than the combined earnings of all 24 of his companions on the 2014 Hip-Hop Cash Kings list.

Earlier this year Apple AAPL +1.56% shelled out $3 billion to purchase Beats, the company founded by Jimmy Iovine and Dr. Dre. Though the latter quickly claimed to be hip-hop’s first billionaire, a nine-figure tax bill means that won’t happen immediately—but he’s well on his way.
