One of iTunes’ least used features must be the star ratings. I’ve never found the urge to pull up the player while listening to make sure I’ve rated what I like or not.
AutoRate is a simple iTunes plugin for Mac that automatically rates each track based on how many times it is listened to or skipped.
Couple this with the Play higher rated songs more often option for Party Shuffle, and your iTunes will learn what you like out of the vast array of pirated music on your hard drive.
