I actually used to listen to rap and most of those artists do tend to be quite serious about changing what wrong with this country and bringing awareness to the problems of the ghetto. BUT, they still idolize and promote the power of the drug trade in the black neighborhoods. Their styles of expression my be somewhat artistic(even that is up to discussion) but still hold the "street" persona on a pedestal. This won't put books in the classrooms of the inner cities and definetly wont put food on their table(but definetly their own).I suggest you look at some other artists, like Mos Def, KRS-1, Common, etc, and not base your opinion on gangster rap. Otherwise, you're making a generalization.
