Would it be possible to get an updated list of implemented tag mappings at [Tag Field Mappings – Mp3tag Documentation](https://docs.mp3tag.de/mapping) please?
I had serious trouble to correctly map the somewhat stupidly named MusicBrainz Picard internal tag "[MusicBrainz Recording ID](http://picard-docs.musicbrainz.org/en/appendices/tag_mapping.html#id21)". While other common MusicBrainz Picard tags are correct mapped, this one isn't. I thought it's "MUSICBRAINZ TRACK ID" because that's how mp3tag is showing that tag written by Picard but when I write that tag with mp3tag, Picard is not recognizing it. I created a mapping for MP4 - MUSICBRAINZ TRACK ID - MUSICBRAINZ\_TRACKID
Turns out, the correct mapping is MP4 - MusicBrainz Track Id - MUSICBRAINZ\_TRACKID

This is the current list of MusicBrainz field mappings:

> As of [Mp3tag v2.91a](https://community.mp3tag.de/t/455), Mp3tag maps the following fields specific to MusicBrainz: MusicBrainz Mp3tag Acoustid Id ACOUSTID\_ID Acoustid Fingerprint ACOUSTID\_FINGERPRINT MusicBrainz Album Id MUSICBRAINZ\_ALBUMID MusicBrainz Album Release Country MUSICBRAINZ\_ALBUMRELEASECOUNTRY MusicBrainz Album Status MUSICBRAINZ\_ALBUMSTATUS MusicBrainz Album Type MUSICBRAINZ\_ALBUMTYPE MusicBrainz Artist Id MUSICBRAINZ\_ARTISTID MusicBrainz Album Artist Id MUSICBRAINZ\_ALBUMARTISTID MusicBrainz O…
`MUSICBRAINZ_TRACKID` is a little special, because it's mapped to the ID3v2 `UFID` (unique file identifier) frame for MP3.
I've made a note to add a dedicated section for MusicBrainz field mappings to the mapping table in the documentation.

Thanks for the list! I see why this one doesn't work for MP4 while the others do.
Could you please add another mapping for MP4, Source: MusicBrainz Track Id, Target MUSICBRAINZ\_TRACKID. That will fix the mapping for this tag for MP4. It already works fine with MP3 and FLAC. Thanks 🙂
