I followed the guides for setting up a Music Library.  Tagged the music files with MusicBrainz PIcard.  For some reason, the files from the 4 Non Blondes - Bigger, Faster, ... show up as "[Missing]" in the Artist list for the stock Windows skin and the Chorus2 web interface. The string "4 Non Blondes" are attached to these tags:  Artist, Album Artist, Album Artist Sort Order, albumartists, Artist Sort Order, Artists, in the FLAC files.  If I remove the "MusicBrainz Artist Id" (efef848b-63e4-4323-8ef7-69a48fbdd51d), and   "MusicBrainz Release Artist Id" (efef848b-63e4-4323-8ef7-69a48fbdd51d) tags and rescan the library, then Kodi displays the Artist name correctly.  This was repeatable.  Picard was used to tag the files again and after another library scan, it is back to displaying "[Missing]" for Artist.

I don't know if this is a Kodi issue or a MusicBrainz issue.  The Id tagged in the files link to the correct artist entry using the MusicBrainz website, https://musicbrainz.org/artist/efef848b-...a48fbdd51d  It's beyond my ability to try and see what comes back via an API call.

Which album did you use to tag your files... https://musicbrainz.org/release-group/0d...14fa325554

[Karellen]

Where exactly are you seeing [Missing Artists]? That usually indicates a tagging problem. I can't replicate the problem with that album...




Do your tags look like this?

[cas206]

As seen here, I start off with the two Artist related MusicBrainz tags removed.



In the Chorus2 interface, I select Music and then Artist under Sections area. The top row, second from left, looks as I expect.



Then I save the MusicBrainz tags to the files, as seen here, and do a Scan Audio Library.



I end up with this. Note the Artist name has changed to [missing].



The same occurs on Kodi Interface on the windows machine that is serving the data to my laptop.  It was just easier to capture screen shots on my laptop.  Select music, then Artists.

Do your tags look like this?

The only difference that I noticed was mine include AcoustID, yours do not.  Yours have Genre set, mine do not.

[Karellen]

Yea, I wondered about the couple of extra tags in your screenshot. I assume there is some setting in musicbrainz picard that I need to enable.
Even in Chorus2 the artist appears for me.

Can you remove all the albums /songs by that artist from your Source. Then run a Music clean library. Make sure it is the Music clean library, and not the Video clean library. Many users get that confused.
Check the artist is removed from the library then move the files back and scan them into the library, with the full tags.
Is it fixed? If not, can you provide the Debug Log of the above process.

[cas206]

I'm in the process of making Debug log files.  I'll try your suggestion first before finishing. But as a preview:
2024-09-26 17:14:43.876 T:5800    debug <general>: CMusicDatabase::UpdateArtistScrapedMBID: Artist mbid efef848b-63e4-4323-8ef7-69a48fbdd51d already assigned to [Missing] (Id: 1)

2024-09-26 17:14:48.037 T:5800    debug <general>: CMusicDatabase::UpdateArtist: Updating 4 Non Blondes (Id: 1170) mbid efef848b-63e4-4323-8ef7-69a48fbdd51d already assigned to [Missing] (Id: 1)

[cas206]

I went to Options>Media, Scrolled down to the "Music" section, and selected "Clean Library".  I verified that the Artist "4 Non Blondes" and the Album "Bigger, Better, ...." are both gone.

However, due to the error message given above, I downloaded DB Browser for SQLite and looked at the MyMusic database. 
The "artist" table contains,
idArtist=1
strArtist=[Missing]
strMusicBrainzArtistID=<The MusicBrainz identifier for 4 Non Blondes>
strSortName="4 Non Blondes"
etc

So it looks like the cleaning did not wipe out this entry which is causing conflict when the title is added back in.

The other place I still see data is table "discography" with idArtist=1 associated with 4 entries with their 4 albums although I only have the one album.  I see in the table that data for all available albums of an artist are stored, not just the ones a user has music files for.

Going to add the music files back and get a log.  Will provide links to them using the instructions.  However, I suspect that I will have to manually delete that entry from the database, or start from scratch and let the database get rebuilt.  I won't do anything though, untill you are done with me collecting data.

Don't know what happened but that first entry should be
 

Code:

[Missing Tag], Artist Tag Missing, [Missing Tag]

Folder with music files removed from source, then Kodi started / stopped.

Folder with music files added back to source. They include all Musicbrainz tags. Kodi started/stopped.

I don't see the error message in the above about the errant database entry. However, the "[Missing]" for the Artist is still showing up in interface.

Here is a prior log with the error message. I believe I just removed the MusicBrainz tags, I didn't do a full removal of the files.

Seeing as how my database seems to be borked, instead of patching it, I'm going to delete and rebuild.

[cas206]

Rebuild of database fixed it.

[scott967]

As I posted before, something had gone wrong in the database to end up with the bad [missing tag] entry.  That was introduced back in the Kodi 17/18 timeframe when the whole music database got an overhaul.  I hope you didn't lose too much creating a fresh library.
