I love the smart playlists and recently I discovered that rating your songs is actually quite useful. The problem is that I can't seem to sort the songs by rating in the smart playlists. I'm setting it up as I want in the edit-screen (sort by rating 5 etc) and close, but when I try to load the playlist no tracks appear in the playlist although I know there are quite a lot of songs which fit the criteria. Then I open the edit-window for the playlist again and then the criteria are changed from sort by rating five to sort unrated songs (if I close the window again, not changing it so it should add all unrated tracks, it works). Why is this happening, and what can I do to solve it?
