I guess I just don't feel like it's really my self-expression, if I just told a generative AI model to create it. I do sometimes create AI art, but I rarely feel like it's worth keeping, since I didn't really put any effort into creating it. There's no emotional connection to the output. In fact I have a wall display which shows a changing painting generated by stable diffusion, but the fun in that is mainly the novelty, not knowing what will be there next time.

Still, I do think you're probably right. Most new music one hears in the radio isn't that great. If you can just create fresh songs of your own liking for every day, then that could be a real threat to that kind of music. But I highly doubt people will stop listening to the great hits of Queen, Bob Marley etc because you can generate similar music with AI.
