id3v2

id3v2 !
Je l'utilise pour les tags de mes mp3 en mode texte. Voici l'aide pour que tu es une idée de ses possibilités :

Usage: id3v2 [OPTION]... [FILE]...
Adds/Modifies/Removes/Views id3v2 tags, modifies/converts/lists id3v1 tags

-h, --help Display this help and exit
-f, --list-frames Display all possible frames for id3v2
-L, --list-genres Lists all id3v1 genres
-v, --version Display version information and exit
-l, --list Lists the tag(s) on the file(s)
-R, --list-rfc822 Lists using an rfc822-style format for output
-d, --delete-v2 Deletes id3v2 tags
-s, --delete-v1 Deletes id3v1 tags
-D, --delete-all Deletes both id3v1 and id3v2 tags
-C, --convert Converts id3v1 tag to id3v2

-2, --id3v2-only Writes only id3v2 tag
-a, --artist "ARTIST" Set the artist information
-A, --album "ALBUM" Set the album title information
-t, --song "SONG" Set the song title information
-c, --comment "DESCRIPTION":"COMMENT":"LANGUAGE"
Set the comment information (both
description and language optional)
-g, --genre num Set the genre number
-y, --year num Set the year
-T, --track num/num Set the track number/(optional) total tracks

You can set the value for any id3v2 frame by using '--' and then frame id
For example:
id3v2 --TIT3 "Monkey!" file.mp3
would set the "Subtitle/Description" frame to "Monkey!".
