The sound quality is excellent. However, the shuffle algorithm is laughably bad and the main reason I intend to drop Apple Music. I have over 12k tracks on my main playlist, but the "shuffle" plays only ~75 of them. Over and over. Similar problem with the customized (your name) radio. You can sort of get around it with Smart Playlists, but those do not sync or appear on other devices like streaming boxes, only on your phone or laptop.

If you don't need a good shuffle feature, it's great. The old disk-based iPod had a great shuffle algorithm, so I'm not sure why Apple decided to get rid of that, but it's truly the worst part of Apple Music. Spotify's shuffle is considerably better, but their sound quality is awful. If they ever get true lossless service (as they've repeatedly promised for years) they could own the category, but they're too stupid and/or greedy to ever do that. There is no single service that gets everything right.
