I am testing this, and have come across one anomaly. Jaikoz 12.6 is setting the “Grouping” field to “Classical” for one of my classical albums. I have set options for Opera work format to Lyrion and “Copy Work to Grouping field” to “no”. I looked in “Never modify these fields”, but “grouping” does not appear in that list.
(This is one which was formerly a false positive for Opera work detection, but is now being correctly detected.)
