One of Microsoft's very own wrote a little diddy based on the Windows XP startup sound (and a few more) and guess what, it beat out the competition on SongFight.org. Listen to it here.  Nice job Jim!

Speaking of startup sounds. A few weeks ago I came across this funny video of a Mac users' startup sound. I think we all know a guy like this. 

As for mine, it's My father for years has had, "It's alllllive... ALLLIVE!!" from Frankenstein as his startup sound (appropriate for Halloween). What's your startup sound/music?
