 | About AutoRate
Sets the rating for all tracks in your iTunes library according to how often each track is played, and how often each track is skipped. The formula uses a combination of play and skip frequency (averaged out over the life of each track), and the play and skip count. Tracks that are frequently skipped are penalised, while often-played tracks are given a higher rating. It uses a 10 bin normal cumulative distribution based histogram to automatically scale the ratings so that the mean rating is ~3. Optionally you can use a linear scale with manual shift, scale factor and mid range skewing.
Both the track play count & skip count are used in conjunction with the length of time each track has been in your library to determine, on a relative basis, how much you like each track. Ratings become dynamic and change with your taste in music following how you listen to your songs. Complete (and meaningful) ratings allow you to quickly select playlists of songs that you like most, or maybe some old classics that need attention. |
