ID3 mass tagger

ID3 mass tagger is a software that enables users to manage audio files with ease. This portable command-line mass tagger is designed for non-interactive adding, updating, or removing of metadata in multiple files with a single command. The software generates tag fields from the filename and can rename files using an intuitive syntax. It currently supports ID3 (1.1) and ID3v2 (2.0, 3.0) tags.

Users can perform a variety of tasks with this software, including adding simple tags to a file, removing all ID3v1 tags from all mp3's, setting genre to "Psychedelic Rock" for all mp3's, and copying ID3v2 tags to ID3v1 tags in all files.

Furthermore, the ID3 mass tagger supports updating tag fields by following a specific syntax, renaming files to a standard "Artist - Title" format using ID3v2 values, and processing multiple directories simultaneously.

Some other features of the software include the ability to swap artist and title fields in all mp3's, copy ID3v1 and ID3v2 tags of a source file to a destination file, and generate a playlist using the best possible text.

The latest release of ID3 mass tagger adds support for Lyrics3 tags, expanding the software's capabilities even further. Overall, ID3 mass tagger is a great tool for managing and organizing audio files efficiently.
