'Smart' playlist adapting

This would help people with giant MP3 collections organize what they actually listen to on their playlists. Example.
Adaptive Playlist is enabled
each song will have an index that is the 'enjoyment factor' of the song
this could easily be calculated like this
each time the song is played, the percentage of the song that is listened to before its changed is recorded in one number, and the number of times the song has been played is recorded in another
then the index of enjoyment would be
total percentage played divided by total times played
so if there was a song i really liked, every time it came up randomly in my playlist, i would listen to it all the way through, so the playtime index is incremented by 100 (because 100% of the song was played), and also the playcount index is incremented by 1, for this time played
then each song would have an enjoyment factor from 1-100, which would be a very accurate indicator of how much you like listening to that song
this index could then be used in a variety of ways, such as biasing the shuffle feature to favor songs with a greater enjoyment index, or even pruning the playlist of all songs with an index below a certain threshhold
whew, that was long
I don't know how hard this would be to implement but it would make organization of many songs much much easier

Well, sometimes you cycle through a playlist by many songs a time, i.e. they get played but switched so fast they're only on for like a couple of milliseconds. So it would have to have a minimum playtime before it took it into the enjoyment index calculation. And you would have to be able to set it back manually, or to whatever you wanted.
