I'm using the latest CD Ripper R16.6, i'm trying to get the UPC (Universal Product Code) as part of the filename, but after 20+ cds, it never returns anything.
Does the tag UPC actually work or am I doing something wrong?.

I'm using the default naming:
[IFVALUE]album artist,[album artist],[IFCOMP]Various Artists[][IF!COMP][artist][][]\[album] ([upc])\[track] [title]
