Apple's recommendations can be ridiculous though. When I go to the "For You" tab in their iOS app here is what is shown as I scroll down
1. Favourites mix - i.e. the music I've played the most
2. Recently played - i.e. the music I've played recently
3. Tuesday's Playlists - the first of any real recommendations so far, but 4 of the 9 album covers it shows in the thumbnails are music I've played recently
4. Heavy Rotation - i.e. music I've played a lot, but not just recently
5. Tuesday's Albums - recommendations based on an artist (Waxahatchee) I've listened to
6. Artist Spotlight Playlists - a selection of playlists, including "Influences" and "Inspired By" playlists by artists that I don't listen to and are really unrelated to most of my collection.
7. New Releases
finally there's the wordy stuff I don't care about, social media posts.
Most of this stuff is not even bad ML (like the "Amazon recommends me vaccuum cleaners because I searched for and bought a vaccuum cleaner" problem) it is just literally showing me what I listened to. I've tried the recommended playlists a handful of times and they don't really show me much new things, they remain pretty unchanged in the weeks or so that I check them.
When you throw in the fact that they periodically delete all of the music I've downloaded, and nuked a chunk of my music collection after I signed up ... I have to say, my experience of Apple Music overall is pretty terrible.
