Academic elites worship blacks and black culture.
When jazz first became a thing the masses of Americans hated it and saw it as degenerate, but the high end literati loved it and promoted it to no end.
Starting in the 1940s the CIA launched the Congress for Cultural Freedom, a think-tank designed to channel funds into the anti-Soviet left. They funded intellectuals, musicians and artists who appeared "leftist" but were actually anti-Marxist and anti-proletarian. This included propping up hideous and meaningless modern "art" as a means of alienating the working-class from the arts and ensuring art could only be appreciated by pompous cultured elites.

There is zero doubt in my mind the CIA has been behind the rise of hip hop for this exact same reason. Hip hop is primarily an anti-working class genre of "music," made by the black lumpenproletariat AKA the criminal underclass. Marx pointed out how the lumpen are an adversary of the genuine working-class, used by the elite classes to offset class struggle. The lumpen in no way threaten the power of cultured elites, hence why they use the lumpen as a substitute revolutionary subject. The Ivory Tower loves and pushes hip hop for this exact reason. The genre is anti-worker, ugly, distorted, chaotic and promotes lumpen and elitist Nietzschean values. (Kendrick Lamar is a good example of this.)
Meanwhile China (a socialist nation) bans rap and gets its school children learning real music, namely classical. They don’t get kids to rap or give them MPCs to learn how to “sample” but give them actual instruments. That’s because real socialism isn’t about romanticizing the gutter but about advancing humanity.
