I have a favorite music player and I really can't stand to use anything else.  And, like most people, I went through the WinAmp days (it's still around of course) and hung out with Windows Media Player; heck I even went through a Real Player phase for a while.  But nothing, I say nothing, compares to Foobar 2000. 

I wish it didn't have such a lousy name, it would be a little easier to recommend to people if it was just called Lite Music player...
