Music: artist with multiple albums of the same work

[philby]

Switching from Plex to Jellyfin, I just noticed that JF mixes up albums when they're similar.
E.g. 2 recodings of Bach's Christmas Oratorio with the same Album artist, one recording from 1987, one from 2024: JF keeps making one album out of this, with each song double.
The recordings release date is set in the AAC metadata, the directory hierarchy is
Music
├── Some Artist
│  ├── Album A 1987
│  │  ├── Song 1.flac
│  │  ├── Song 2.flac
│  │  └── Song 3.flac
│  └── Album A 2024
│      ├── Track 1.m4a
│      ├── Track 2.m4a
│      └── Track 3.m4a

Is there a way to get JF to make two albums out of this, preferably without having to go and identify each song through Musicbrainz separately?

Thanks!

File naming and folder structure matters much less than metadata tags.

Are your files properly tagged? I'm assuming you have two Albums with the same name, but one is a remaster?

If they have the same album name in the metadata tags, Jellyfin would mix them together as you've described. Does not matter if the release date is different.

Nevermind – found the error. Synology DSM must have merged the folders, all the files were in 1 directory.
Separated those, and for good measure added the date to the album name in tags.

They are separate recordings, not remasters – that's quite common for classical music, e.g. Herbert von Karajan recorded the Beethoven Symphonies multiple times in his career.
