Art is subjective. It sounds like AI music did evoke an emotional response from OP, which IMO is also just as important of what we define as the purpose of art: evoking emotion and awe from consuming art. A connection is being made from the creator to the consumer. I view AI as merely another tool to that means.

Human expression with art can go both ways from producing and experiencing.

Just because its not art doesn't mean its not funny or interesting to listen to.

Bird's aren't making art when they sing, I still like listening to birds. Why can't the sounds AI make be in the same category.

Discussions about music always boil down to “stop liking what I don’t like!”.
