[Raion]

Rap is poetry, not music. It has no harmonics or melody, little instrumentation, little to no singing (spoken word, rather) and has little regard for musical scales or established rules of music. 

The fact that it's poetry, albeit often encompassing subjects that are often disgusting and materialistic (e.g. drugs, misogyny, homophobia, material money and riches, polygamy/player lifestyle) is overlooked by the media. Yes, I'm biased. I dislike it, think it's garbage most of the time and a bad influence to the youths moreso than rock or metal ever were. But it's poetry, just not very good in that it relies on borrowed samples, repetitiveness, and spoken word. This applies to basically all rap, fwiw. Not just NWA, not just Eminem. 

So back to music, music has at least a rhythm and singing, whether it's an ancient Hurrian prayers, Muslim chants, African tribal chants, Gregorian chants, classical, rock, punk, ska, reggae etc. It sometimes has instruments (something that's absent in Islam for instance) or sometimes has percussion. It always has rhythm and singing. Rap does sometimes include singing, either chorus or samples, but if the majority of the song isn't, it's not music. If the majority of the song is borrowed samples, alongside spoken word, it's not music.

What do you think people?
