Any way to disable "auto rating" feature in iTunes 8.2?

I've noticed something really annoying in iTunes 8.x. I use star ratings on all of my tracks to create playlists. For example, the playlist I take with me on my iPhone is all the tracks rated three stars or better.

Starting sometime recently iTunes will automatically rate the other songs on an album if I have rated any of the songs.

So, if I rate a Snow Patrol song 3 stars, iTunes will rate the whole albums 3 "hollow" stars (they look like the regular stars but are hollow to tell you that iTunes did it).

Is there some way to turn this off? It's seriously annoying and is messing up my mobile tunes playlist which is based off of star ratings.

Thanks!

 

The only item in the smart playlist criteria says;

Rating is greater than ** (two stars).

These hollow stars count for that since the tracks automatically rated by iTunes are showing up in my playlist.

If there's no ability to stop iTunes from automatically giving star ratings to songs then there should be.
