On a related note, I have a hypothesis about why AI does not (currently) seem to do well in classifying music genres. It depends on examples of human classifications to learn from. My conjecture is that the AI classifications are probably very good, but that the human classifications are faulty, and that might explain why AI doesn't seem to do well. For example, the AI is given a largish database of music which is pre-labeled by genre according to humans. The AI then tries to figure out the rules of classification from that database. My hypothesis is that humans are not very good at that, and thus the AI is hamstrung before it even gets started.
Interesting.

Do you have a source for AI being bad at classifying music?

Re. your hypothesis, last sentence especially, it doesn't square with the idea I had (from old reads) that neural networks were very good at fishing signal out of noise.
But then AI and NN aren't the same thing.

One example, from an annual competition:

An accuracy of 76 percent is not "bad", but I do not consider it "doing well" either.

They are generally good at fishing signal out of noise, but only if given good data to fish from.

GIGO is still a thing. How accurate is the human data fed into the AI? I have not seen any scores on that.

I haven't played chess since the time my 8-year old son beat me in a legitimate game which I wasn't trying to lose.

I watched that game the other day. Awesome.

Currently watching the jose raul capablanca series (1901) on agadmator's channel. Capablanca had no formal training and knew no theory on opening or end games. He kicked ass.
