This concept seems very viable to me. After all, when selecting music
we are somewhat less interested in it's context (for music tracks at
least). In the very least, that is not where the users (eye)focus is.
So why not use this multi column track selection UI instead of
PopUpDropper and let it cover the contextview. The deeper in the
hierarchy you go the less far you have to drag to the playlistview.
