Just in point of fact, allowing easy access to add tracks to the playlist was 
only one of the ideas behind the PUD.  Allowing easy access to add tracks to 
(other collections, burnable CDs, media devices, organizing folders, etc) 
were also ideas.  I doubt with the new context view with Plasma that anything 
will ever come of it, but who knows some day...
