I don't adhere to the Chinese room idea, and I don't think that there are any musical limitations on what an AI can do. I'm saying that audiences like music for more than its merits; they often fantasize about the singer/songwriter, in the case of popular music, or become invested in knowing about the composer in the case of more rarefied styles. A lot of people will just lose interest in a piece of music as soon as they find out it was generated. It's the same reason art forgers are treated as criminals rather than artistic geniuses in their own right.

No one will know. You're completely missing the point. People aren't going to say "DISCLAIMER THIS WAS WRITTEN BY AI". They'll just claim it as theirs. My entire point is that it's now convincing enough that you'll have no idea. People are already using it.

Audiences as a whole don't give a shit about the making of the music, at least as far as liking the music goes. "I like this song, but there is no story behind it, so I don't like it now" is just not a thing. People like to dance and sing along.

You can just make up some bullshit anyway, which is usually the case. Stop putting musicians on a pedestal. You've fallen into the trap of image. It's mostly fake. They are just people.
