VLC
Better yet, what exactly is your issue with iTunes?
iTunes is the software incarnation of Satan, Voldemort, Saddam Hussein, and Big Bird all combined. I don't see how anyone could stand to use it for anything except to access their fancy Apple mobile devices, and even that is hard sometimes.
i use winamp for music
Also don't use VLC, it's complete stuff for audio. It somehow makes it all detuned.
Yeah, like the first 6-12 seconds of a song is out of pitch under Windows. It's recognized as a bug.
