Personally, it matters to me quite a lot where art comes from, especially music. I have a hard time "separating the art from the artist". If I find out a musician is a creep/abuser/rapist, I can't enjoy their music anymore.

This belief obviously isn't widespread given artists like Michael Jackson, Chris Brown, R. Kelly, and Jimmy Page are still wildly popular. But I assume I'm not alone in this.

As for AI music, it's hard for me to imagine an "AI Musician" ever becoming very popular because I reckon most humans want some human-ness in their music. And I think if an existing artist ever put out AI music as their own, they'd lose some fans pretty quickly.
