As much as I loathe rap music now and what it represents, I think actual crime is the smallest affect of rap music.
I don't think people are listening to rap music, and then their heads start spinning on some Exorcist ish, and then they're motivated to go shoot or kill somebody.
Theirs soooooo many other negative affects that rap music is having specifically on the black community that I could type up a novel.
Direct crime would actually be near the bottom of the list. Rap music is killing us in so many other ways on some spiritual ish.
BUT with that said, you gotta be a complete idiot in my opinion to not think that the LIFESTYLE glorified in the genre (which also happens to be the world's most popular artform) has absolutely ZERO affect on CERTAIN people (mainly easily manipulated youth from bad environments) , and is tricking them and making it seem like living that thug, street life is "cool"
Drill Rap is damn near the only thing going into the minds of some people and it's injecting a literal demonic spirit inside of them. Atleast some of us balance it out with other forms of positive media, but others, no. All genocide rap and negativity.
