For me both Apple Music and Spotify work quite well on both iOS and Android, however there are a few things to consider:
- Apple Music contains less trackers on Android than Spotify does
- Apple Music pays artists way more than Spotify
- Spotify is from the EU, which may or may not be important to you (for me it’s a plus)
- Spotify provides both music and podcasts, which Apple Music does not do.
So depending on what’s most important to you, one can be better than the other
Edit: I realize that it’s not a Spotify vs Apple Music thread, so to answer your original question: Apple Music on Android is something I use myself and I like this setup, works very well for me.
Plus, if you have a family cloud and a spare slot, you can create a new user that you will use only on Android Apple Music, so that the IPs are not connected to your iPhone identity. The playlists you want to sync would then need to be shared with the new user, so a little bit of friction there.
