I would think they would want to listen to it for the same reason they listen to human generated music.
Is your thought here that AI generated art is not art? Is it the nature of the creator that determines the listeners enjoyment? If the music generated by a computer is indistinguishable from human made music, how can this be possible? Moreover, at what point would the computer generation be sufficient to shift it from art to “screensaver”? Would it be one simulated member of an otherwise human orchestra? Would it take 50%. If you can’t draw a line, doesn’t that further indicate it’s irrelevant?
