Apple Music is so much more baked into the Apple ecosystem, isn’t a rip off (as I might expect), and doesn’t have crappy selection (as I was afraid of — it has pretty much all of the niche stuff I didn’t expect it to).
iCloud and Apple Music are just part of the device purchase for me tbh. The whole thing is supposed to work together, and it does for the most part.
Someone mentioned regional licensing issues on Apple Music, which makes sense. I have not seen that yet in the US.
I believe that the catalogue in Spotify is a bit better, at least I didn't see "this song is not available in your country" messages in Spotify. In Apple Music I see it all the time.
I am a huge Apple fan, but Spotify is better in so many ways (Discover weekly and other lists like “piano ballads” - which while not perfect are better than I get on Apple Music)
Maybe it’s because my wife and I share music lists or something but the recommendation engine in Apple Music is not good for me.
