I'm switching between these apps for a while but I am always ending with Spotify again ...
The discovery functions in Spotify are great. Everytime a weekly playlist or mix gets updated I find some new songs which I like. In Apple Music I rarely find some new music. The 'For you' tab is a joke.
What's great about AM is the seemless iOS experience and of course Siri. I also love how I can add some songs to my library (upload them) and change every album art I don't like
. AM offers a bigger library of songs and for example kpop.
But that's it really.
I'm listening to music most of the time on my iMac and using iTunes for Music is really really horrible. It's nowhere near as smooth as the Spotify desktop client, you can't click on Artists and albums in the songs list (except while surfing the 'New' tab).
Aaaaand last but not least – at least in Germany – I get spammed with german music especially german rap which I absolutely can't stand!!! Almost every week a new german singer/rapper gets promoted heavily and the weekly playlists are full of german (c)rap. Maybe this is related to the taste of the majority in Germany, but there should be at least the option to get rid of stuff like that...
In Spotify there is much less german music and I can use the 'New Music Friday' playlists of other countries as well as I can switch the country to a english speaking one.
However the biggest issue I have with Apple Music is that when I put a song in both my library and a playlist (or first in a playlist and add it to my library later) and delete the song one day from my library it also gets deleted from every single playlist. I also miss the drag and drop in iTunes to add new songs to a playlist while in the 'New' tab.
