OmniNerd has an interesting discussion on the stastics behind iTunes' Party Shuffle feature, which allows users to play back higher-rated songs more often. The author looks at how star ratings affect playback counts: "For the rating-biased trial the preference algorithm appears to be linear from 12% to 27% for the rated songs.

While one star may seem like the lowest rating, no-rating proved the black sheep of the lot."
