Confusing format string

What is the difference between:
Artist.displayFormat={$artist$orchestra}
and:
Title.displayFormat={$title^$date} ?

This is taken from your examples in the user guide. Why has the second string an '^' character between $title and $date?

The first of these contains a single format item and the second contains two format items. Within each format item, duplicate values are eliminated automatically (for example, if there are Artist and Orchestra tags with the same value).

Quote:You write that each occuring '^' character denotes the prefix, postfix and separator - in this order. How does this match with the format string Title.displayFormat={$title^$date}?

Any prefix/suffix/separator that isn't specified has its default value. The default for prefix and suffix is the empty string and the default for separator is a comma followed by a space.

Quote:And what format string would I need to just append let's say an 'x' to the tag? It should be {$tag^^x}

This is correct as long as the tag has only a single value. You have specified an empty prefix, a suffix value of x and the default separator.
