Rapping has obviously come a long way since the days of “Rapper’s Delight” and guys like Sugarhill Gang or Kool Moe Dee. In fact when it comes to the music business, rap is clearly one of the most popular and lucrative genres in the industry. So much so that it’s more like a label or a business than it ever has been. And it’s creating more millionaires than it ever has. And some rappers today are way more than just that. They are their own brands. Take Diddy and Jay Z for example. These guys don’t just rap anymore. They have countless other labels of their own including clothing lines, production companies, alcohol brands, and even sports talent. Just to show you how wealthy these guys become, take a look at the 20 richest rappers in the world in the pages that follow. The number figures are courtesy of Celebrity Net Worth.
