This is a terribly unpopular opinion to express here on MacRumours, so I am braced for the usual incoming hate mail/death threats/fatwahs etc…
IMHO, Spotify is much better than Apple Music.
Main thing is I can control Spotify on my Mac by using the iPhone app. I come in from outside listening to something on Spotify and it picks up and continues on my Mac. Seamless.
You Cannot do this with Apple Music. It is not possible…
I have had Spotify for many years and cannot fault the suggestions of new music etc.
Spotify understands/has learnt I don't want to or need to listen to Hip Hop/Urban whatever that crap is that Apple keeps suggesting to me. (But if that is your thing, then by god, Apple will help you fill your needs.
I listen to Classical mostly and while Apple has the same catalogue as Spotify, the search function is dismal — often incomplete and just plain wrongly catalogued.
