Cool iTunes feature

I've never tried it before, but iTunes can fix scratched CDs. I found that out on accident because I have a copy of OK Computer by Radiohead that has been scratched since day 1. I was moving it over to my iPod and discovered that it fixed the scratched tracks. So now, I'm re-burning--having imported the tracks as .wav files, whereby, they are fixed. I'm now going to try it with some other discs. I'm sure it won't work for all, but if even a few are fixed, I'll be thrilled.
