Music: people need playlists

[MorrisJobke]

(This is kind of a major thing to change in the music app.) Currently a big problem with Music is that there is only one collection (main view) and one play queue (left list). Instead, people should be able to have playlists, which are shown in the left list, and the collection or the respective content of the playlist should be shown in the main content.

For reference, check out how http://youtify.com and http://spotify.com do it.
