I’ll install this tonight. I was hoping for a slick and pukka Apple variant on the Audioscrobbler idea, with tighter integration into itunes and ipod. I listen to my mp3s almost entirely on the ipod, and its a chore to get them onto audioscrobbler, only to find that the boogers on audioscrobbler/last.fm choose to wipe the cache of recent tracks every nanosecond or so.
