Dr. Dre is the highest-paid act in hip hop, earning $620 million.
The rap mogul's enormous pre-tax profits mostly come from his sale of his Beats Audio headphone range to Apple earlier this year.
The deal - which saw Apple buy the company for $3 billion - meant Dr. Dre had the total highest annual earnings of any star ever as well as topping Forbes magazine's annual Hip Hop Cash Kings list.
DJ Khaled, who placed 20th, told the publication: ''It's safe to say headphones is a good business''.
The top five was completed by rapper Drake and Macklemore and Ryan Lewis who earned $33 million and $32 million respectively.
The only female to make the list was 'Superbass' hitmaker Nicki Minaj, who took the 11th spot after earning $14 million.
