ID3 mass tagger is a portable command-line mass tagger for audio files. It is designed for non-interactively adding, removing, or updating meta-information in a number of files with a single command. It can generate tag fields from the filename and rename files using an intuitive syntax. It currently supports ID3 (1.1), Lyrics3 (2.0), and ID3v2 (2.0 and 3.0) tags.
