Does system restore work on something that big? You could try it. I would reccomend that you make as little changes to your system as possible. If you really did "delete" them they are still there. When you tell windoze to delete something all it does is rename it so it can't recognize it, its still there until it is overwritten. You can go to
Download.com to find an undelete program to find these files and restore them. I have
Norton SystemWorks, it has AV protection, undelete, regestry doctor, and other useful system tools, I reccomend it. NOTE: all of the songs might not still be there, as some may have already been overwritten. Good luck.
