That guy is an idiot. Someone engages him and tries to point out that even within styles some music is objectively better, and the guy refuses to even acknowledge that it's possible for songs or artists to be objectively better. Guy is an idiot.

It's possible to try and make a point without getting instantly painted into a corner by your dying need to dissent with every single point your critics raise. Lol

Just goes to show, using 'white people bad' as the foundation of your reasoning doesn't make for a very strong position to defend.
