Right now, the concepts of album and playlist in AT are somehow interchangeable. Except the playlist automatically generated by the website's music player, users can only create albums both for publishing music and for collecting it. I'd allow users to create playlists as well in addition to albums. The reason is that playlists and albums serve different purposes. An album is a collection of tracks by one or more artists meant to be released as a unity or individual artistic work. A playlist is more a collection of music selected by the listener by any arbitrary criteria.
