yes, the mixtapes helped but in my opinion half of his hype right now is from Eminem. but i will say it again : he's okay, i'll give the album a listen and if it's good i'll pick it up.
50's gotta keep Murda Inc. out his mouth though, he has like 10 tracks talkin about them. this is the one beef that is 100% real right now, and shits only gonna get bigger too.
