So here is a list of tags that seem to be dedicated esp. to iTunes, MP4-wise:
https://picard-docs.musicbrainz.org/downloads/MusicBrainz_Picard_Tag_Map.html
The following tags I’d like to show within iTunes/Apple Music but are simply not there to show/select?
----:com.apple.iTunes:CATALOGNUMBER
----:com.apple.iTunes:CONDUCTOR
----:com.apple.iTunes:initialkey
----:com.apple.iTunes:ISRC
----:com.apple.iTunes:LYRICIST
----:com.apple.iTunes:DJMIXER
----:com.apple.iTunes:MIXER
----:com.apple.iTunes:MOOD
----:com.apple.iTunes:PRODUCER
----:com.apple.iTunes:LABEL
----:com.apple.iTunes:REMIXER
----:com.apple.iTunes:SUBTITLE
See example in iTunes.
See example in Apple Music.
Can someone tell me why are these called ----:com.apple.iTunes:
while they can’t be shown in iTunes?
