If/when the AI music gets good enough, how will you know the difference? I find small artists on spotify all the time that I enjoy and there's no way to know anything about their creative process.
The level of enjoyment I get from art is looking into the artist, their background, and anything else surrounding the work that can add meaning to it for me. Even small artists have these, and it's easier than ever to connect with artists on this level thanks to the internet.
All to say is sure at a glance it may sound/look the same, but that's only part of the joy of art.
