An Introduction to Tags
Quod Libet supports free-form tags for most of the common audio formats. This means you can name your tags in any way you want, but using common tag names for common purposes is advised because it helps QL to write the tags in a way that other media players can understand them and also helps QL understand certain tag values and make use of them.
Quod Libet also supports expressions using “tied tags” in several contexts - see Tied Tags
(including roles) will be used for sorting if they are present.
Lets say you have a song with an
artist tag The Beatles and want it
to be sorted as if it was named Beatles, The, you can add an
artistsort tag containing Beatles, The.
QL includes a basic plugin for creating such sort tags automatically.
The musicbrainz plugin includes an option to write sort tags if found.
A programmatic tag is one typically added by either Quod Libet / Ex Falso or
another program and not designed for human consumption. Examples are
musicbrainz_albumid. Note that to see
these, you must turn on “Show programmatic tags” in the relevant
Internal tags are tags that start with a
~year. They are either not stored in files themselves, or are derived
from the values in the files.
See Internal Tags for a complete list.
Quod Libet supports performer roles, which let you associate a performer in a
song with a specific instrument. To use this feature, name a tag
performer:role. Quod Libet will display the roles alongside the names in
Quod Libet uses various tags to define what songs are in the same album.
For songs to be in the same album, both
albumartist have to
be the same. In addition the first non-empty value of the following tags have
to match (checked in this order):
‘’I have a two disc album and each disc is shown separately.’’
Make sure the album tags (and
albumsort if present) (remove ‘CD1/2’ etc.)
and albumartist tags are the same.
‘’Two albums have the same name and are merged.’’
Add an albumartist tag for at least one of them.
‘’Why doesn’t QL know that my albums are different ones by seeing that they don’t have the same artist?’’
There are many songs that have multiple artist, so this can’t be decided on the basis of artist tags.
