I migrate from WMP to J River  
I used Format Value JR/PEOPLE : %ARTIST% as J River don't support all WMA tags  
This failed as ARTIST has multiple values and I only got the first one.

META\_SEP(artist,😉 did the trick

None of the meta functions are listed under Functions in the interface.  
I suggest to include them as well

Kind regards
