Just buy a month of premium ($10/month or $5 if you're a student) and try it.
I actually find Spotify apps to be far worse than iTunes at least on iOS. And the Apple Watch app for Apple Music is really impressive.
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.
The albums I haven't listened to in a while and might want to listen to again according to the app are those I listen to daily.
New releases are not sorted or filtered by genre, so I guess it is great that some pop or reggae artist has a new album out when I only listen to metal on Spotify?
Etc., etc... in other words - I use Spotify for totally unrelated reasons and switched from Google Play Music, but it has all the same faults, it just works better for some part of the target group, but it is in now way perfect, or even good, with regards to their recommendation engine either.
I hope Spotify fixes their security woes. Either way I have no reason to leave Apple Music now.
