This is really annoying, it totally messes up my smart playlists that rely on song ratings for selection. If I make a smart playlist that chooses songs that are rated in the range of 4 to 5 stars iTunes is now using the greyed out album ratings in addition to song ratings to make the selections. This is totally messing up my playlists because I'm getting songs added that I haven't even rated at all. If you look at the screen grab you can see I've got those grey album rated songs that iTunes automatically generated included in this playlist. I never use album ratings.
