I have a semi-related question. Musicbrainz Picard sometimes adds a tag called 'Disc Subtitle' to my flac files. Inside the .flac file, the tag is saved under the name DISCSUBTITLE.
Now, I want to show that DISCSUBTITLE tag as sub-header in Musicbee. The tag doesn't show up by default in Musicbee, but it's one of the standard available custom tags. According to this table https://musicbee.fandom.com/wiki/Custom_Tags
Musicbee's Set Subtitle is identical to DISCSUBTITLE in Vorbis. So, I've set up my Custom 1 tag as Set Subtitle and selected Set Subtitle as sub-header. But... Nothing shows up.
Have I done something wrong? Did I forget something?
(As a sidenote, the set subtitle is also empty in the tag-edit window in Musicbee, even though I'm sure my files have a DISCSUBTITLE tag...)
EDIT: Ok, I think I figured it out. Musicbee is NOT saving Set Subtitle as DISCSUBTITLE in flac files. It is, in fact, saving (and thus, I assume reading) it as SETSUBTITLE. That table is clearly wrong.
So, now my question is... How can I use Picard's tag DISCSUBTITLE as sub-header? I know very little about Musicbee's custom and virtual tags so....
