Why do most black guys only like rap?Watch
Secondly it is an incredibly black based music genre. Just like the blues were, except unlike the blues white poeple didn't start doing it themselves and getting massively popular off the back of it(ie rock music) and taking it over. For whatever reason rap has remained largely a black based form of music.
Actually, rap music can be very uplifting, especially for black people as we are still oppressed today. Artists such as Kendrick Lamar gives us hope such as his song ‘Alright’ and not all rappers promote violence so yeah you are dismissed
Man, I miss London. But yeah, you shouldn't assume that just because they like rap they only like rap. When you get older, that often proves to not be the case for anyone with even the slightest hint of a personality. And black guys often do have quite the personality.
