Rappers rap over other rappers beats for mixtapes. If you checkout the 50 Cent/G-Unit mixtape library, you will find that these guys shit out a full lenght mixtape every fuckin week! Its a way for them to stay in the game and get at people they need to get at untill the next album comes out.
This isnt something new, its been happening for a long time and I dont see a problem with it unless they release it on an actual album.
O yea, I make good beats too.
