There is usually no need to remove the so called ID3 tags of audio files. Actually there are only two scenarios that do make sense. The first is if you encounter lots of audio files with wrong ID3 tags and the second if you want to remove either ID3v1 or ID3v2 tags from the audio files to ensure that all use the same tagging method. ID3 tags make it possible to store meta data in audio files. Meta data includes the song title, the album and artist among other information.
ID3 Kill is a free Windows software that can recursively scan through directories and perform file operations on audio files.
Usage is pretty straightforward. You point it at a directory and check a few boxes to configure the options. It is possible to include subdirectories in the scan. The main options are to remove ID3v1 and / or ID3v2 tags from all encountered audio files.

Other options include to clean m3u and pls playlists, to ignore file attributes or to display a message after the run is finished.

mp3tag does a great job removing tags and adding them too :)
For tagging mp3s I use another German software, ID3-TagIT, excellent, which handles everything including ID removal. But ID3KILL will come in handy immediately here since I know I have some mp3s still tagged ID3v1 as well, whilst I wish to have them all only ID3v2 tagged, and that batch processing will be the best solution.
Thanks is not enough
