Ok, now heres somthing that you guys probably never noticed. See, I find myself installing XP all the time on different machines. If theres anything that I noticed, it was... When XP has fully installed, and is on the screen "Setting up your computer" (The screen that has you set up your user accounts, ect...), that song is the song playing.
Now you guys know why that song is there. It is used in the initial setup!
