I'm not really for or against mac's, obviously that elitist crap is wrong, but being against something just because you don't like most of the people that use one is dumb.
I use itunes.
If I come across a good media player that no stereotype uses, i'll let you know.
Songbird looks like the closest match, i don't use it, but it looks good.
Songbird - Open Source Music Player
Edit : Just trying songbird now, it seems like a cross between winamp and itunes, the best thing about it is that its open source.
