Dave Mark, writing for The Loop:
To me, the biggest issue with Apple Music is the depth of the user experience. For example, with For You, the on-boarding is primitive, at best. I never felt steered towards my deepest musical tastes. And as I listened to music, even as I diligently favorited my best loved tunes, I never felt that For You really got me.
As someone who came from Spotify to Apple Music I can say that Dave is right on. Apple Music is terrible at recommendations and even worse at surfacing music through Playlists. When you use Spotify for even a short period of time you realize the competition isn't even close.
Apple has one advantage currently; integrated lock-in. You're part of Apple's ecosystem. But they really need to step up their game.
