Help to understand haw tag management work

[Calaat]

Moode accumulates the Performer, Conductor and Artist into the Artist tag and displays these values as a comma separated list in the first line of each track in the track list. The Composer(s) if any are displayed on the second line.

What's a bit confusing to me is that your sample Album "Cartoon Darkness" only shows 1 artist tag in MusicBrainZ Picard.

If you select a track, yo get all the tags you see on my shot: https://imgur.com/a/27Albuv

Yes I see that but it only shows 1 artist but your earlier screen shot of Moode's "Audio info" showed multiple artists.

What you see in the Track info listing is metadata after it has passed through MPD and moOde routines.

When I'm diagnosing metadata issues I prefer to see what's actually encoded in the file containing the audio track.

In the case of FLAC files, the tool metaflac is useful (and included in every moOde installation). We want to see only the metadata, which is encoded in a Vorbis comment block and there is an option to do just that.

As an example, here's the command applied to the Stereo Test track included in every moOde installation:

Code:

rho@moode914:~ $ metaflac --list --block-type=VORBIS_COMMENT /mnt/SDCARD/'Stereo Test'/LRMonoPhase4.flac
METADATA block #2
 type: 4 (VORBIS_COMMENT)
 is last: false
 length: 322
 vendor string: reference libFLAC 1.3.1 20141125

   comment[10]: TITLESORT=LR Channel And Phase
   comment[11]: ARTISTSORT=Koz
   comment[12]: ALBUMSORT=Stereo Test
rho@moode914:~ $

IMHO, the concept of "artist" is laughably ill-defined. I wish musicologists had banded together to define some sensible metadata fields before digital distribution of audio became a thing, but it didn't happen.

There are no multiple artists. It is what i'm trying to say all the time. There are the names of the group individuals, as i show you in my shot: https://imgur.com/a/AsF5i2qhttps://imgH7
There are Lyricist, Composer and artists in my release. You are showing just the top, and ignoring the rest or we are loading different releases.

Thank you, it is quite that indeed. 
Anyways, i will retag all the library, using a systematized way. I have a really hard lack of consistency.

MPD just extracts the tags in the file and moode displays them. In the case of "Artist" moode accumulates Artist, Performer and Conductor tags into the Artist column.

I'm still confused.

Can you post a link to the MusicBrainZ release for that Album that has those tags? 
I could not find it and it would be helpful to me in case I have to troubleshoot a similar issue.

Here is an example from my collection that shows what I think is going on here:
Artist in moOde shows a long list of individuals, with the actual value of the Artist tag at the end.
   
In MusicBrainz, these other individuals are listed in various Performer tags.
   
Can a case be made perhaps for a preference of "Artist (strict)" that omits the performer and conductor tags and just shows whatever is in the Artist tags?

Right, but I can't find any tags listed in MusicBrainz for the 4 releases of Cartoon Darkness by Amyl and the Sniffers. https://musicbrainz.org/release-group/32...3ad7956092

If I load these releases into Picard the only tags relating to artist names are Artist, Album Artist, and Artists. They are all set to "Amyl and the Sniffers".

In the OP screen shot there are 4 additional artists listed and so I asked where they came from.

Sorry for the delay, I live in València, and internet is quite unstable this days.

The concrete case of my release of Amyl and the Sniffers, after a few work on, i figure out the tags were introduced by Qobuz and not by Musicbrainz. So, there is not a Musicbrainz id that load this tags.

My first question was, exactly, what Betrum says. Anyways, i have start a massive retag to introduce some genre tags and RS gain, i will fix the performers.

Thanks for the support.
