It is a well known "limitation" of Bliss that it has the potential to "break" playlists...but playlists themselves are a pain to create - particularly in XBMC for example.

Seeing as Bliss knows where the files are (and when it changes things) it would be great to be able to define and edit playlists from within Bliss. Create a playlist, tick which tracks you want in it; automatically shuffle them etc, and output in a chosen format to a specified file location. Every time Bliss makes a change that would other wise break a playlist, it could create a fresh one.

Loosely linked to Music Management, but still would be very useful for me. I love playlists for background music, but I hate creating them...and this seems better as a server app than a desktop one.
