For the media_list there is an other object called media_list_view.  
You can have a flat view, or a hierarchical view. Sorted view are not  
implemented though. This is conceptually and practically nice. And it  
helps to correctly layers the different objects.

I think you should offer the same kind of abilities, that is having  
multiple objects to represent the "viewed" playlist.
