You can hardly compare "Elvis, the Pelvis" with this seriously raunchy, violent, hateful cRap 'music'.
Seriously? Have you even tried to look up adults'/parents' responses to Elvis back in the day? I'd say "raunchy" certainly came up.
Look, the point is that too many people still confuse quality with taste. If you don't like the entire genre, then rap is clearly not your taste and you have no basis from which to judge its quality.
It's really no different than a punk teenager on a skateboard saying, "Classical? Opera?? They SUCK!" Well, he has no way to judge the quality of classical or opera music, because he obviously hates both generes in totality. Works the same way in either direction.
To those who can't stand rap, great! Admit that you don't like rap. Leave it at that. It's pointless noise to compare two genres of music, since the differences are inherently a matter of musical taste!
