Remove Personal Information From iTunes Plus Music Tracks

There was much consternation when iTunes Plus lovers discovered that their DRM-free music downloads came packaged with hidden user data, including their name and email address. While that's one way to discourage filesharing, it also opens up the possibility of innocent people getting sued by the RIAA.

If you're bothered that your personal information is being stored in your iTunes Plus music tracks, you can use the free software, Privatunes, to erase it one track at a time. Unfortunately, there's no bulk anonymizing option. It's also Windows only.
