Right-click the item you want to rate, point to RateSelectedItems, and then click one of the ratings, or click Unrated.
One star is the lowest rating. Five stars is the highest rating.
Notes
By default, all items in Media Library are automatically given a rating of three stars. These auto ratings change based on the number of times the item is played. The three-star auto rating is also used when you click Unrated.
When you rate an item, that rating replaces the auto rating in the Rating column in MediaLibrary. Your rating is listed as My Rating in the criteria for auto playlists. You can use both the Auto Rating and the My Rating criteria to create auto playlists.
A filled star indicates that the star is selected; an empty star indicates that the star is not selected.
If the Media Library database becomes corrupted, your files and most of the media information should remain intact. Rating and play count information may be lost because it is not stored in the files.
