Why is there so much wrong with rap?

I mean all it is is some tone deaf retard who claims he's from "the hood" talking about how much money he got, how many b*tches he's f**ked, and how much weed he smoked. There's no real instruments in rap and it takes no talent whatsoever. Not like metal, where you actually need to be able to sing and play an instrument. Rap is for people who can't even carry a tune and don't have enough money for autotune but wanna be in the music business. All rappers get shot or die of AIDS and there has never been an intelligent or talented rapper in the history of music.
