I quit Spotify when the “New Library Experience” completely fucked the music library side of the app. If you mostly use playlists, it was a lateral change. If you used it to collect some songs here, and album there, and keep them all sorted, it’s like it dumped your entire collection on the floor and expected a thank-you for the new organization system.
My guess, as others have mentioned, is that Spotify tries to squeeze more profits by pushing certain songs, whether because they get paid to promote them, or the royalties are lower. That’s easier to do with their playlists and recommendations, so they pushed people to that side of the app by making everything else dogshit. And now, apparently, the curated side took it too far and is awful, too.
I still use Apple Music, which is one of like two services that actually let you organize your music in a sensible way outside of playlists. That said, after I cut cords with video streaming services and set up my own library, I think I might do the same with music.
