well i dont know if anyone knew this or not before but i made smart playlists on my old 5gig
one with whats been played more then 5 times
one that has whats been played less then 5 times
one with whats been played in the last day
and while it doenst update on the ipod, it will update once i connect it to itunes. so the songs i like i can play them a couple of times more and they go to the play list of whats been played more then 5 times, and the ones i play in a day i can see if i liked any of them
but id still like the new feature of the new ipods and im sure its possible
