taged is a commandline utility that can create and modify ID3 data,
usually found in .mp3 files. Besides supporting text frames like
artist, title, track number, etc., it also supports attached pictures,
play counters, and generated playlists. It aims at being quick and
easy to use when many tags needs to be created/updated, and handles
regular expression matching of tag data from filenames, as well as
renaming files based on the tags.
