I've tried to switch to Spotify from Apple Music a few times because the common wisdom seems to be that Spotify has better algorithmic recommendations. But Apple Music "knows" what I like already, and Spotify never grabs me so fast that I'm willing to stick around for weeks training it -- and I suspect part of that is all of Apple Music's human-made playlists. Apple Music has hired a lot of good editors/curators over the years, and I haven't found any service -- including audiophile darlings Qobuz and Tidal -- that beats it in that aspect.

If I search for random songs Apple Music immediately starts suggesting similar songs. I'd prefer only added or liked music be used as signals.

For me curation was better but I was really missing the ability to quickly seed a playlist with a specific vibe and build from there for specific moods.

That, and the desktop app and confusion between library and Apple Music streaming was annoying to manage. They need to unify that experience or split it completely.
