I would think something like this would work better:

%ARTISTS:${VALUE},|%%ALBUMS:${VALUE},|%%KEYS:${VALUE},|%%SOURCE_TYPES:${VALUE},|%%CUSTOM%

That uses the value and ends it with a comma but only if it's non-empty

Thanks very much Mark, almost perfect! It is possible to avoid the string ends with a "," if it is not valued the following field?
Now, if CUSTOM is not set, each string of one or more fields ends with "," eg.
Artist, Album, Key,
