As bearish as I am on AI, outside of the agent deciding it only wants to play "Semi Charmed Life" and nothing else, I fail to see how this is a nightmarish hellscape in and of itself.

I feel standard commercial radio is already that hellscape. I mostly listen to rock (classic or alternative radio stations) and it's the same ~20 things being rinsed and repeated every hour and every day. Has been this way for decades.

I am pretty sure 90% of playlists you hear when out and about are generated by spotify algorithms at this point. I would more be concerned because it seems like a weird use for LLM when recommendation engines are probably better than it? I suppose it has a ton of training data around music forums and people recommending songs, but it is hard to believe that would beat out billions of hours of tracked listening spotify has access too.
