Directives: chorus
This directive indicates that the song chorus must be played here.
Examples:
{chorus}
{chorus: label="Final"}
In the second form, if config setting settings.choruslabels is true (default)
the argument is used as a label for the chorus.
If settings.choruslabels is false, the argument is used instead of
the normal Chorus tag.
For legacy purposes you can leave out the label property and just
include the label text
{chorus: Final}
