Just a throught: I really do think Apple should fix up some sort of anonymous ratings feedback system for iTunes.
It could be pretty useful. iTunes could take your rating data anonymously, which could be used for:
- iTunes music store popularity (popularity is probably disproportionate to ratings)
- music industry album feedback (I bet artists would love to see what their audience likes and lothes)
- podcast track popularity (again, podcast producers could nail down the episodes which their audience likes most and do more of the same).
I think that would be great. Last FM almost does this, but even there track rating ≠how much you listen to a track.
