Kanye West is an artist first and foremost, but with his albums he's proven that he is a major moneymaker, as well. His "Glow in the Dark" tour is sold out all over the place, and it doesn't seem like a stretch that a concert promoter like Live Nation would turn their attention to him. If there's one rapper in the game whose popularity I don't see fizzling out anytime soon, it's Kanye. But will that ego and overly emotional thing he has going on get in the way of making good business decisions? Most definitely. At least he'll always have his "big brother" to look up to.

Diddy is a businessman and mogul, of course. But to call him a rapper is a bit of a stretch, despite the albums in his discography. He's worth a lot but has always seemed more interested in his own personal fame than that of his artists. Investing hundreds of millions in the future of Bad Boy Records is… I don't know. Danity Kane and Day 26 both opened at number one, so you never know.

With that insane Vitamin Water business, his record label, his clothing line, and all of the other various consumer products he has a hand in, he is certainly a rapper/mogul in the vein of Diddy and Jay-Z. But he lost that big Kanye battle! He may be gazillionaire and set for life, but will any huge company trust that people will be interested in what he has to say at 48? Is anyone truly interested in what he has to say now?

Oh, Nas. He's not much interested in business. If was, he would be topping Fortune lists with Diddy, 50 Cent, and Jay-Z right now. Instead, he's content to smoke weed with Kelis and put out hyper-controversial albums. Rumor has it that he and Jay-Z will release and album together when the Carter Music Group gets off the ground, so he'll be along for the ride.

Lil Wayne will tell anyone who listens that he is either the next Jay-Z or better than Jay-Z, but the relative young'un is close to blowing his career before it's reached its full potential. While 50 Cent and Jay-Z picked up rap after they were finished ratcheting up their illegal street cred, which also serves as fodder for their music, Wayne, who has been on the road with Cash Money since he was a young teenager, seems desperate to prove himself by consuming tons of illegal drugs and getting himself arrested. Not the sort of behavior that inspires anyone to invest $150 million.

Snoop has been around for a long time, and, with "Sexual Seduction," has proven that there's still a major market for his music. I don't think he's going anywhere anytime soon. But he's Snoop. His business ideas include a line of grocery stores called Snoopermarkets. 'Nuff said.
