Dr Dre's $620m earnings equal the pay of nine other top artists

Dr Dre has taken home an enormous amount of money this year.

The size of each artist's money is proportional to the amount of money they took home in the last year, we can see the details of money from the following datas.

Beyonce--$115m                       Justin Bieber--$80m                     Calvin Harris--$66m

One direction--$75m                Taylor Swift--$64m                         Diddy--$60

Jay Z--$60m                                Bruno Mars--$60m                        Katy Perry--$40m

The $620m (£395m) he made before tax, which means he has topped Forbes' list of the biggest earners in music in 2014.

Not only that, but he has now also got the Forbes record for the highest earnings in a single year by any musician.

The majority of his cash has come not from record sales but from Apple's purchase of Beats, the company he founded, for $3bn (£1.9bn).

Best known for their headphone range, Beats also makes technology used in car audio systems and has a music streaming service known as Beats Music.

Priced about $300 (£191) in the US, Dr Dre, if he were so inclined, could buy more than two million sets of his Studio headphones with his earnings.
