Flac tags, missing and/or duplicate tags

[hovgaard]

In some FLAC files the field 'Album artist' is empty, but when I look onto the tags with another tag editor (MusicBrainz) I see there is data in a tag names 'album artist' (note the lower case first letter). Some files have both 'Album artist' and 'album artist' and it looks like mp3tag only handle the one with uppercase first letter. Are I am missing something here ?

What does the extended tags dialogue Alt-T show?
The tag field should be called ALBUMARTIST in MP3tag.

Extended Tag Dialog shows the 'missing' field. Guess I have to 'play' with the 'Adjust visibilty of the columns' dialog ?

I would use a mapping to map ALBUM ARTIST to ALBUMARTIST.
See Options Ctrl-O Tags>Mapping.

How to map ALBUMARTIST TO ALBUM ARTIST for flac files

Could someone please briefly walk me through how to create a mapping that will cause any edits I make to the ALBUMARTIST field in a FLAC file to also apply to the ALBUM ARTIST field? I'm having an issue with the way Media monkey is interpreting these tags and this seems the fastest way to fix the issue. Thanks.
