I would like to know if it is possible to choose which fields are printed when the list command is used? For instance, I would like the duration of each track to be printed in addition to the artist, album, and title.
To specify the format from the command line you can use the
-f option (list command documentation).
To set the default format for the list command use format_item in your configuration. You might want something like
format_item $artist - $album - $title - $length
Have a look at
beet fields for other things you can include.
I knew it was something simple, but it is hard to search for.
