lltag is a frontend to tag (and rename) mp3/ogg/flac files automagically. It uses mp3info, vorbiscomment and metaflac to do so.
lltag takes a list of music files on the command line and tries to automatically understand their filenames and guess their associated tags. It uses an internal format database to do so. For each file, it will try each format until one matches the current filename, extract the corresponding fields from the filename and set the music tags.
lltag also allows to pass one or several format strings like "%a - %A/%n. - %t", so that the user may help the program when the filenames are too strange, complex or damaged.
It is also possible to set some fields by hand or edit some. And finally, lltag may use these fields to rename the file according to a user-given filename format.
lltag also provides a interface to access an online CDDB (TrackType.org) and retrieve tags from there. It makes it possible to tag/rename a file from scratch.
This command line will ask lltag to process all files in the music/ subdirectory, with two formats (which discards the first directory name using the %i opcode) and force the genre to Rock. lltag starts with the understanding of the user-passed format strings. It then processes each file and tries each format until one matches.
mycomputer:~/% lltag -F "%i/%n. %a - %t" -F "%i/%a - %t" -g Rock music/*

This command will make lltag try one user-defined format and then try to guess. It additionally removes the path during matching, replaces _ with spaces in tags, and accepts multiples spaces instead of one. Moreover, tagging is done recursively in all subdirectories.
mycomputer:~/% lltag --format "%n=%a=%t" -G -R * --nopath --sep _ --spaces

Tagging.
This command makes lltag only guess (no user-specified formats) and never ask for confirmation before tagging.
mycomputer:~/% lltag -G */*/*/* --yes
Processing file "music/Grandaddy/Grandaddy - First Album/Grandaddy - Revolution.ogg"...
Trying to parse filename with internal formats...
'%a/%a - %A/%a - %t' matches this file...

The following example uses lltag to retrieve tags from CDDB with the interactive interface, tags the file, and renames it according a user-provided format. The output has been truncated for sake of concision (the usage should actually appear with first occurence of each menu, and there may be more CDDB results).
mycomputer:~/% lltag --cddb myfile.mp3
Processing file "myfile.mp3"...
