Dr. Dre has this year been named the highest-paid musician by Forbes magazine.
Topping the financial bible's annual list after he picked up a staggering $620 million in the last 12 months, it is largely due to the sale to Apple of his Beat Electronics company.
His huge fortune puts Beyoncé into second place with $115 million, though she's one of only two other stars to earn over $100 million, with The Eagles in third place taking home that sum exactly, thanks to a world tour.
Bon Jovi came in at fourth place with earnings of $82 million and attributed their fortune to being "efficient" and keeping their entourage costs as low as possible.
Frontman Jon Bon Jovi explained: "I think it's just wise to be efficient. I know big bands where each of them have personal assistants on the road, each of them has a security guard. We don't have a security guard. Take your own friggin' bags!"
Bruce Springsteen rounded out the top five, just $1 million behind Bon Jovi with $81 million.
Justin Bieber, One Direction, Sir Paul McCartney, Calvin Harris and Toby Keith rounded out the top 10.
