I hate AI slop as much as the next guy, but I will say this: I'm almost old enough to retire, and I can't remember a time when the radio wasn't playing completely terrible music made by uninspired employees or machines for purely commercial purposes 90% of the time.
For every Beattles, there's a hundred Backstreet Boys. Over time, the good music stays and the not-so-good music is rightfully forgotten. That's why music from the past always seems to be so much better than the shit that plays on the radio today. But crucially, it was the same amount of shit back then too.
AI is just the latest iterative process in the shit music industry. If there's any good AI music, you'll know when people still listen to it in 20 years. It's too early to tell.
