Is there anything wrong here, or that's expected behaviour?
I found #6, which implies multi-disc albums are well supported on LMS.

Hello,
Sorry for late response. For now, the only reliable way to group these discs is to use a musicbrainz release id.
If this tag is not present, only the files in the same directory are considered to be part of the same album (and if the name of the album is the same, of course)

[awsms]

Mhh.. so LMS relies a LOT on MusicBrainz's metadata, as it's also the case for the dupechecker which simply checks a MB track id (and probably other things I haven't found yet).
Shouldn't it be mentioned somewhere in the README? Because I pretty much assumed by reading it setting the same album tag & same album artist for files would group them (like it's the case with navidrome for ex.)

[epoupon]

Yes, it relies a lot on MB (and it is assumed). You are right, this should be better stated in the readme file.
That being said, we can try to improve the fallback behavior to handle more use cases :)

[awsms]

Hi again! So after pulling the docker image for the latest build, I did a force library rescan.
However, I'm still seeing multi-discs albums as multiple albums instead.

[epoupon]

Hello!
What is the layout of the offending album?

[awsms]

Exactly the same as in the OP, I haven't changed it since:

Ah I may have badly written a test.

Would you mind testing this?
remove the album/scan (not full)/readd the album/scan (not full)
And tell me how it goes?

[awsms]

After moving the album to somewhere outside of the library folder, rescan, re-move it to the library folder, then rescan : it works!

[epoupon]

Ok, so it works but the migration is not handled :(
