Nigeria's Hip-Hop Industry Is Booming More Than USA?

Saw this on Worldstarhiphop.com. It's pretty interesting the way Hip Hop has spread globally. I wonder what the chance is for a Nigerian Emcee to gain crossover appeal in the states. I'm sure they would have a built in following what with the immigrants here. Its kinda crazy that they are making a hundred thou a concert when rappers over here struggle to make ten thou for a show. Big Ups to all my Nigerian friends.
