Jay-Z has topped a list of the richest rappers in music for the second year running.

The hip-hop star, real name Shawn Carter, earned $63million in the 12 months up to July from his music, business deals and endorsements.

Diddy was second on Forbes list with $30million, while Akon ($21m), Lil' Wayne ($20m) and ($17m) completed the top-five.

Surpisingly, Eminem only managed to earn $8million, despite the success of recent album 'Recovery'.

List compiler Zack O'Malley Greenburg said: "It's pretty shocking to see him so low down on the list. Compared to his peers, he doesn't really do much outside of music."

Snoop Dogg and Kanye West also featured on the countdown.
