Dude, I'm not sure what you're trying to do; I think you know how to wipe files, so are you just trying to wipe the file contents and keep the files?
Most likely you are much smarter about this than me, but if I knew what your desired end results were I might could help. (Either that or I could just scoff at you!).

It's a program that automatically goes through your itunes library and adds missing cover art, missing or incorrect title/album/artist data, corrects misspelled words, etc. I have about 70GB worth of tunes, probably at least 40% of which is messed up in one way or another. So I sure don't want to go through and fix them all manually.
