Clever audio playback program?

Is there anything out there that will let me set my preferences of music style, and then play similar stuff? Like itunes star rating only more clever? For example I could rate 1 track by Muse as awesome, and then it would play similar stuff from my collection? and then learn my preferences the more I rate music?

Any ideas?

Thanks

Josh

Winamp does
http://www.winamp.com
I have never actually used the feature, but the program is free so worth a try :)
right click on the track in the media library and it gives you the option to
'Play similar tracks to ....'

Another bonus, I dont know if its just me, but winamps audio output is much clearer and better quality than other media players

Thanks - I think it's got everything I want - ability to rate individual tracks (like itunes) and the play similar feature looks good :)

No worries dude, Ive never gone back to any other media player after using winamp, unfortunately it has a stupidly cheesy intro the first time you start it up. Quite funny though :P
