Duplicates Of (some) Files In Music Folder?

I'm having an issue with some of the files being duplicated in my music folder. I've noticed that only the first 20-30 artists have been duplicated. The originals are still there, however the contents inside (so the albums of the artist) have duplicated/cloned into my music folder.So I can find the album Razors Edge in :Users--MusicACDC and in :Users--Music When I go to options in Razors Edge album in :Users--Music, it says that the location is actually :Users--MusicACDC. So it's as if both point to the same location.
However, when I delete the duplicate (the album that's just in My Music folder), the deletes the original (in My MusicACDCRazors Edge) and then the song won't play at all in Itunes or Windows Media. Then when I restore the album from Recycling Bin, it works.

Additionally, Itunes says that there are no duplicates...I would also like to add: when I copy ACDC from My Music onto my desktop, the duplicates remain in My Music. When I try to copy the duplicates into my ACDC folder, it says "The destination folder is the same as the source folder". When I delete the duplicate files, it still deletes the originals that or on the desktop
