Was it though? Don't think a lot of people go to Spotify for the quality but rather a lot of their other features, widespread support and discovery. Will take Apple a long time to catch up on that. The people caring about quality already have a ton of options outside of Spotify.
I've given Apple Music a try a few times. Every time, I've dropped it and gone back to Spotify — not because of the audio quality or network effects or anything, but just because the Apple Music UX is so freaking terrible. I don't doubt that this will sound amazing, but that will still not overcome the UI issues.
