Have any of you ever used "The Filter" to create playlists on iTunes (or whatever you use)? You can also get it to recommend music you might like based on the music you already own. That's the main reason I got it. Pandora and LastFM say they do that - but I have yet to discover something I actually LOVE from either of them.
So far I like it. Been playing with it for an hour - this is what single women who love music and don't have a social life do on Friday nights. Trust me, its NOT my first choice.
