This tool removes every kind of trash from your mp3-files. It searches for valid mp3 audiodata-frames and removes everything else. This has the big advantage that it will also remove tags which are in the middle of the file (as is the case with joined tracks) as well as broken frames (half-downloads) and malicious tags (Tag-buffer-overflow bug in WinAMP and Windows XP). Use this tool to cleanup your mp3 files before you add your own tag. No more double tags, or annoying ‘Lyrics’ data containing group names or misspelled song names.
