I don't have a ton of hope just yet because I think it's still an incentives problem rather than a technical one.

I got tired of the increasing AI slop in my YouTube Music feed and switched to Deezer a few months ago. Since then, not a single AI artist I've been able to spot. If a relatively marginal player like that can manage it, why can't Spotify or YTM? My suspicion is simply that Deezer actually actually tries.

It's the same problem with Google and search. Kagi and others have demonstrated that you can produce better results with an infinitesimal fraction of the budget, and Google is still plenty competent where they care to be. This won't start to get fixed until they see a financial incentive to do so.
