Windows XP moving some of my audio tracks glitch

I use a PC running Windows XP SP2. Fully updated.

I currently have 25 Windows Media audio tracks saved in my 'My Music'
folder. None of them protected. Every few days or so, Windows (or some
program) will move one or two of these audio tracks, usually the same ones,
and place them in a folder called 'Unknown Artist.' Those audio tracks
still play fine, but this forces me to move them back with the rest of the
audio tracks. Then I delete the 'Unknown Artist' folder.

Why does this keep happening?
