Editor: The ID3KILL project has been cancelled for now. By the time I wrote it, there were no good removal tools for ID3 tags available. Today, I see no reason to continue and I don't have the time to maintain and update ID3KILL as much as I'd want to. I will eventually release a revised version with a few updated functions, but basically ID3KILL will stay like it is now.
If you still want to use ID3KILL, you can download the latest version 1.4 here. Make sure that you have a few megabytes of free space on the drive you're using!
One of my favorite tag removal programs is Tag, a free, open-source solution.
Its features are:
View tags
Generate tags from FileNames
Modify tag values manually
Tag files with information read from CDDB files
Copy tags from one file to another
Convert tags to different format
Remove tags
Rename Files based on tag information
Move files to directories generated from tag values
Generate Winamp playlists (optionally with AlbumList extensions and playing times)
Generate text files with information about tracks and album (format customizable)
Decode files and name output using tag information
Test mode that shows what would happen without actually doing anything to files.
