The mobile app really needs a feature to view the albums or artist inside a playlist. I hate this playlist thing, I don't want to create PLs, I just want to download what I want to listen. The other annoying thing is when I download a playlist on a computer and try to sync it with my iPhone the musics aren't copied directly to the phone, instead it downloads again on the device.
I cancel my premium subscription and go to use Rdio until this gets fixed.
This will be possible with the new Spotify Collection feature which is currently in beta. It should hopefully be rolled out to everyone soon. 😉
