I sympathize with this experience, but I’m not quite sure why you “need” to quit your streaming services in order to achieve the desired effect. I almost exclusively use Spotify, but I use it to listen to new releases from artists I like, listen to way more albums then I could afford to buy physically, and check out music my friends recommend to me. You don’t have to use streaming services as a playlist aggregator, there’s nothing stopping you from actively enjoying music on there.
My optimistic outlook is that most of the musical spaces I reside in will likely shun or be immune to whatever norms develop regarding AI. I personally care deeply about the fact that the music I listen to is made deliberately and thoughtfully by a human being, and I like to think there are many others who feel the same way.
More cynically though, I’m worried about AI taking market share away from music “made by humans”. If this becomes the norm, maybe there just won’t be money in doing things the old fashioned way. Maybe the type of musicians I want to listen to would be discouraged from making music in this new climate.
