They've got to sort the playlists out, they're what make Spotify so good.
Right now, if you create a playlist it adds all the songs to your music library rather than just stream them from the store as you play. I don't want my 500 song playlist to result in 500 new albums under "My Music" - that's shitty.
I also tried importing an iTunes compatible playlist file and it will only match the songs already in my library. It doesn't search Apple Music to fill in the gaps.
Apple Music also needs to introduce collaborative playlists. The best thing about Spotify is you can publically share your playlist, and they are searchable within Spotify too so you stumble across some awesome ones.
