Music content is synced to Kodi from deselected libraries

Discussed on this reddit thread: https://www.reddit.com/r/jellyfin/comments/dfdafp/kodi_addon_ignores_or_syncs_wrong_libraries/

Describe the bug
When importing music libraries, the way the addon seems to extract from Jellyfin database results in content not in the selected library being pulled over.

To Reproduce
Populate multiple music libraries. Compilation albums seem to be the main contributor to the issue.

Library A
\
  - Artist A
  \
    - Album 1
    \ - Title

Library B
  - Album 2
  \
    \  - Artist A - Title
       - Artist B - Title
       - Artist C - Title

In Jellyfin for Kodi, select only Library A to be imported.

Expected behavior
Kodi should only import content actually included in the Libraries selected.

Actual behavior
Artists, Albums and Tracks from content not existing in the selected libraries is synced over to Kodi. In the above example, not only does the track from Artist A on Album 2 get synced, but the entirety of Album 2 is pulled over as well.

When the sync is occurring you can follow in the top-right and see the Artist / Album / Title being copied over. It seems that even if Artist A only appears in one track on an album, it pulls over the entire album e.g. "Bee Gees / Now That's What I Call Music X / [every single track]". As a side note, this may also be causing significant performance loss because the same album is pulled multiple times, once for each unique artist that appears in the album.

System (please complete the following information):

• OS: NVIDIA Shield TV 8.0.1
• Jellyfin Version: 10.4.0
• Kodi Version: 18.4
• Addon Version: 0.3.4

Unfortunately, this seems to be a limitation of the API right now. I'm pretty sure I can code around it, though. Quick question though: Can you confirm that you're seeing this in the Web client as well? My test filestructure right now is:

- Library1
  - ArtistA
    - AlbumA
    - AlbumB
- Library2
  - ArtistA
    - AlbumC
    - AlbumD

And if I browse to just ArtistA in the web client in either library, I get a list of all 4 albums

Yes, that's correct. That doesn't directly match my use case / what my libraries look like, but for the one artist I know that would be the case for 'W.A. Mozart', I do indeed see albums in the 'Albums' listing (not 'Also appears on' - I think that wouldn't be a problem) that extend beyond the library I initially clicked into.

Removing access to the other library immediately fixes it and I only see what I would expect to see.

Fantastic work! Great job thank you! The performance improvements quoted are remarkable!

I can't promise that it's 100% fixed, but just judging by the API calls it should be fixed. We're hoping for another release this coming week, so we'll find out soon(ish)
