This well fits with the feature request of bringing back "smart playlists". 
Unlike the dynamic playlists, these are created according to some criteria 
when dragging them to the playlist editor and then they are static. I would 
really like to see them back, to do things like getting a list of unrated 
songs. It would also fit here: The dynamic playlist editor could get (if it 
does not already have that) a way to choose the set of songs it chooses from, 
and that set could be a smart playlist containing all songs which are unrated 
or have a rating of 5.

Kind regards,
Ralf Jung
