You're right as far as your choices. It is 40, Quinn, and Keak. Ya Boy is on the come up but does not really have a radio hit that gets any kind of spin right now. F.A.B. can be up there, N.E.W. Oakland and Kicked out the Club is getting regular spins, and The Team/C. Carson are doing it right now too but not of the same level as Quinn, Keak, or 40. But if all you care about is albums sold and downloaded, I think you need to rethink your reason to listen to this music, albums sold and downloaded isnt shit compared to how people feel the music. On this board alone, the Team is popular as fuck but their album sales don't reflect it, dont mean they aint hot.
