Tried my hardest to give it a good try today. Didn't work. Lots of minor things here and there, the worst complaints being about the long load times for songs and the terrible statusbar color/blending.
I agree.... I give it the positive of the doubt still sinds I've got three months free period to try everything out.... So far my experiences:
+ the white / light look and feel is very nice, much better then Spotify
+ the possibility to add your own cover art to a playlist is awesome
+ lot's of songs and albums but.... see also the "-"
+ suggestions based on your taste are pretty amazing, better then Spotify
- There is much to say about the user interface, which of many points things are not that positive. It takes a while to get used on how everything works and that's a bad thing since Apple "used" to simplify thing rather then to complicate things.
- not al albums or songs are there, even worse, some of the albums I used to listen to frequently are simply not there while on Spotify they are.... that's a huge minus
- Lack of radio stations, based on my taste I only got 1 electronic station listed, I rely on other platforms when dealing with radiostations which have much more to offer then Apple
- search on my device or within Apple Music Library is illustrated with two red looking bars, it's a minor thing but with all that empty space below it looks to me that this specific design element has been created in a rush...
I'm just playing with it for two days now so it's to early to give a final judgement, but it's clear that there are enough points for Apple to deal with.
