When it comes to making waves in the rap game, being on television all the time doesn't hurt. (Just ask Will Smith).
Actor Donald Glover (a.k.a. Childish Gambino) is already an underground sensation whose independent album CAMP sold well, and he already has enough fans to sell out a joint comedy/music tour across the country.
He's already starring in season two of Girls next year. All he needs is one big song to break out in music, too. We're betting that he can make it happen.
