Windows ID3 Editor

From Pa-software:

Windows ID3 Editor is a small and simple MP3 tag editor, which offers the ability to edit the most wanted attributes of the ID3 tags in one window. Although iTunes offers a good interface for editing tags, it does have a few important attributes missing, copyright and encoded by which is where ID3 Editor saves the day. MP3 ID3 tags are used to store important information of a music track, such as the track title, track number, artist, album. The information can then be displayed in your favorite MP3 player application or on your portable player such as an iPod, a Walkman or other music hardware.

You can also add a copyright, URL and encode by this will ensure your audience knows where the track originated from. Editing albums is made easy by the option to edit them as a group. This opens the selected MP3's into one window rather than opening them individually.
