Now admittedly I'm not going to spend much time investigating this but "hip-hop can be very melodic"?   That is an interesting proposition.

I'm willing to dedicate about 3 minutes listening to a hip-hop song deemed to be melodic.    Can you cite one we can call up on YouTube? Please don't say we have to buy it.   That's unconstitutional--cruel and unusual punishment.


"loud, abrasive, and noisy" and "expressing disgust".   That would be" Won't Get Fooled Again", probably the best rock song ever.    But most punk doesn't seem to come close to that standard--a lot is just noise. If you want to protest, it helps if the listener can understand the lyrics.
