Rap is just disgusting. RnB has taken after rap and is just as crass now. Hip hop used to be a respectable form of music particularly when it was more based on politics. It never was popular among other folk and it never will be. It was born from sampling other records and even if the lyrics were clean, to other people it just wouldn't be "real music" because of the sampling. People think sampling is easy. Trust me, I used to sample, it isn't.
Anyway what hip hop eventually turned to and what it is today is pure vile horse manure and RnB has gone the same route. Twerking everywhere, nonsense lyrics, evil imagery. A cesspool really
