MusicBrainz Picard/Tags

From MusicBrainz Wiki

This page describes both Tags (which are saved inside your music files and can be read by your music player) and Picard variables which can be used in Picard scripts (for tagging, for file renaming and in several other more minor settings).

All tags are also available as variables, but additional variables which start with '_' are not saved as Tags within your music files.

Variable are used in scripts by wrapping the name between '%' character e.g. '%title%'.

Some variables can contain more than one value (for example, musicbrainz_artistid), and if you want to use only one of the values then you will need to use special script functions to access / set them. To access all the multiple values at one, use the variable normally and Picard will combine them into a single string separated by ; .


Basic Tags

The following tags are populated from MusicBrainz data for most releases, without any special Picard settings.

All of these are also available as variables for use in Picard Scripts (for tagging, for file renaming and in several other more minor settings) by wrapping them between '%' symbols e.g. '%title%'.

Other Information

For technical details on how these tags are written into files, see Picard Tag Mapping.

For ID3 based tags i.e. mp3 files, you can set ID3 tags directly from your scripts by setting a special variable starting '_id3:'. Currently only ID3 comment (TXXX) frames are supported using '%_id3:TXXX:<description>%', for example $copy(_id3:TXXX:PERFORMERSORTORDER,artistsort). (Since Picard 0.9)
