In v2.89 you did the following change:
> [2018-06-04] CHG: added mappings for special fields with MusicBrainz IDs for ID3v2 and MP4. (#18405)
Can I ask if you could add more mappings of MusicBrainz fields? The following fields would need to be changed from
TXXX:ACOUSTID ID
TXXX:MUSICBRAINZ ALBUM RELEASE COUNTRY
TXXX:MUSICBRAINZ ALBUM STATUS
TXXX:MUSICBRAINZ ALBUM TYPE
into
TXXX:Acoustid Id
TXXX:MusicBrainz Album Release Country
TXXX:MusicBrainz Album Status
TXXX:MusicBrainz Album Type
and also changed in the extended tags **display** into
ACOUSTID\_ID
MUSICBRAINZ\_ALBUMRELEASECOUNTRY
MUSICBRAINZ\_ALBUMSTATUS
MUSICBRAINZ\_ALBUMTYPE
I'm using ID3v2.4 UTF-8 setting. Thanks so much for implementing this, greatly appreciated!

As far as I understand the user-defined fields (that start with TXXX) the name of that field is set during creation.
So
> [@culinko](#):
>
> TXXX:ACOUSTID ID
and
> [@culinko](#):

> ACOUSTID\_ID
would actually be 2 different fields.
If you want to map these, see File\>Options\>Tags\>Mapping

@culinko
Are you sure about this?
In [your other thread](https://community.mp3tag.de/t/some-txxx-tags-are-written-in-lowercase/43847) you ask to write tags in all uppercase, but here, you ask for some kind of "title case"?
What's the difference between this MusicBrainz tags and TXXX tags in general?

I probably confused you with the Extended tags bit, I just mean for display purposes. I added the "display" word into my initial post.
What I mean is that after MusicBrainz tags got their special mixed case mappings in Mp3Tag v2.89, they are displayed in all caps and with underscores in Extended Tags, so I just wanted the 4 tags that I mentioned to be displayed the same way so it would be consistent for all MusicBrainz tags (yes, AcoustID is also a MusicBrainz tag, I asked a current Picard dev about that).
What I mean is this: [https://i.imgur.com/KZ7LZkf.png](https://i.imgur.com/KZ7LZkf.png), you can see the missing underscores not being displayed for the tags there. Also I'm not sure about whether they should be displayed as MUSICBRAINZ\_ALBUM\_RELEASE\_COUNTRY or MUSICBRAINZ\_ALBUMRELEASECOUNTRY, but I think Florian named the current tags so he can decide how they should be named. Anyway the Extended Tags display is not that big of a deal, I just like things to be consistent and couldn't not notice this 🙂

I think this is similar to what was already changed for other MusicBrainz defined tags like `MusicBrainz Artist Id`. These are specifically defined tags with a specific meaning, and their casing should be preserved. MP3Tag already contains a fixed mapping of most of those tags, but not for the ones @culinko mentioned above. See also this older discussion:
> [@Problem when entering MusicBrainz IDs (e.g., MusicBrainz Artist ID)](https://community.mp3tag.de/t/problem-when-entering-musicbrainz-ids-e-g-musicbrainz-artist-id/43258/2):

> This is due to a change in v2.89 for the internal mapping of MusicBrainz IDs [2018-06-04] CHG: added mappings for special fields with MusicBrainz IDs for ID3v2 and MP4. ([#18405](https://community.mp3tag.de/t/18405)) With this change, I've added an mapping from internal (written to the tag) to external (displayed in Mp3tag) representation of the MusicBrainz ID fields. This was necessary, because other applications (e.g., MusicBrainz Picard) or libraries (e.g., TagLib) are using different names for those identifiers depending on t…

Yes, I'll add them to the next release. Thanks for pointing.

Hi Florian,
Jaikoz/SongKong developer here. We have a nice spreadsheet that we share with phw that keeps mappings for different formats for Picard/Jaikoz/SongKong. We really like to try and keep compatible with other tagger applications like Mp3tag so I share with you hoping it will be useful to you [https://docs.google.com/spreadsheets/d/1afugW3R1FRDN-mwt5SQLY4R7aLAu3RqzjN3pR1497Ok/edit?usp=sharing](https://docs.google.com/spreadsheets/d/1afugW3R1FRDN-mwt5SQLY4R7aLAu3RqzjN3pR1497Ok/edit?usp=sharing) and will help to improve compatability between applications.

As of [Mp3tag v2.91a](https://community.mp3tag.de/t/455), Mp3tag maps the following fields specific to MusicBrainz:
| MusicBrainz | Mp3tag |

| Acoustid Fingerprint | ACOUSTID\_FINGERPRINT |
| MusicBrainz Album Id | MUSICBRAINZ\_ALBUMID |

| MusicBrainz Album Status | MUSICBRAINZ\_ALBUMSTATUS |
| MusicBrainz Album Type | MUSICBRAINZ\_ALBUMTYPE |
| MusicBrainz Artist Id | MUSICBRAINZ\_ARTISTID |
| MusicBrainz Album Artist Id | MUSICBRAINZ\_ALBUMARTISTID |
| MusicBrainz Original Album Id | MUSICBRAINZ\_ORIGINALALBUMID |
| MusicBrainz Original Artist Id | MUSICBRAINZ\_ORIGINALARTISTID |
| MusicBrainz Release Group Id | MUSICBRAINZ\_RELEASEGROUPID |

| MusicBrainz Work Id | MUSICBRAINZ\_WORKID |
| MusicBrainz TRM Id | MUSICBRAINZ\_TRMID |
| `UFID://musicbrainz.org` | MUSICBRAINZ\_TRACKID |

Thanks for this change @Florian.
Can it be, that the first two fields are not yet listed in "Erweiterte Felder"?

I've added the fields to the extended fields list with [Mp3tag v2.91b](https://community.mp3tag.de/t/455).
