This is strange. Taking a break from reading posts in this thread, my eyes happened to fall upon the banner ad for FixTunes that happened to be at the top of this very same page. Just in case it's not at the top as you read this, it says:
Automatically fix your misspelled and incorrect song details and add album artwork to music. No typing necessary. It's automatic. Free download.

Anybody tried it?
