wierd music in legacy

for some reason legacy is playing the music from other games that are on the computer. a few months ago it was playing the music from my little brothers atlantis game (not bad music, BTW). when he stopped playing and uninstalled it, the music became normal. now legacy is playing the music from daikatana. anybody have this happen to them?

Wild stab in the dark time...

Legacy plays CD music. If there is a CD in the drive, it plays it. What's in your CD drive?
