Two albums, by different artists "entangled" in Emby

[brothom 200]

I have these two albums:

K:\Media\Music\Katy Perry - 2008 - One Of The Boys
...
K:\Media\Music\Lana Del Rey - 2023 - Did you know that there’s a tunnel under Ocean Blvd

Both these albums have their Artist and Contributing Artist and Album set accordingly.
The years also match and track numbers are applied correctly.

I don't know how, or why. Emby merges these two albums into some kind of amalgamation, using the cover from one, the artist name from the other and just bunches these two random folders together:

I've already tried to:

Rename folder
Move all songs of both artists out of the library, scan, and add them in one by one and scan
Moved the folders to different parent foldes (so they have their own artist parent folder), scan
Remove one artist, scan, add artist back in, scan
Manually edit the ID's (they always point to either one or the other)

An example of the files (within mp3tag) are:

This issue is driving me absolutely bonkers. Any clues?

Hey, have you checked Extended Tags in Mp3tag for any anomalies???

And, I guess you have probably tried scanning the virtual albums in Emby???

I'm happy to test the files on my set up, to see what occurs, if you get really stuck.

No worries, ether way...

@user24that was a great suggestion! Aparently both these albums had a bunch of MusicBrainz tags which were butchered beyond belief.

I don't think Emby actually adds the MusicBrainz ID's to the files right? 

Now I can finally listen to Lana Del Rey without being interrupted by Katy Perry's lesbian explorations!

Correct (I think).  Emby only adds them into the Emby database for certain fields, if MusicBrainz fetchers are enabled for that library. Emby will also import the embedded ones that are there already.

Depending on where your Music came from in the first place, there could be incorrect embedded MusicBrainz tags or other rogue tags that don't show up in the default Mp3tag views - therefore always check Extended Tags!!! 

It's easy enough to add MusicBrainz tags using MusicBrainz as a Tag source in Mp3tag (or via Picard), but also easy to mess it up!!!

BTW, I'm more than happy to bypass the KP explorations too!!!

@user24true true. I tend to correct any faulty data before adding them to my library but perhaps I'll need to be more thorough.

It still strikes me as strange that files from different folder, with different albums and different artists and different years, become "merged" due to these tags.

I'd expect there to be some continuity check / failsafe mechanism in place to prevent exactly this scenario. I'm also wondering Emby would look at these tags in the first place if it's not "actually using" them.

The only post referring to this is one from 2001: 

The Music Naming page does mention supporting tags but not explictely which ones: https://emby.media/support/articles/Music-Naming.html

> Emby should support all common tags written by Musicbrainz Picard.

I'd rather see to it that this actually doesn't happen and that it doesn't read from MusicBrainz tags in my case. So the next question would be;

How can we prevent Emby from reading from MusicBrainz tags.
