Can you confirm that the bug noted in the comment for the lines you changed is fixed on Jellyfin?

Because if you remove those lines, that will reintroduce a different bug.

[atirna]

the comment's bug was about the old query, not this one.

the filter (d9da588, #2041) covered AlbumIds: query.id, which Jellyfin matches by id or album name (the getSongList bodge documents the same), so same-named releases leaked. bf501da then switched this request to ParentId: query.id for #2111: descendants of the album item only, no name matching. since then the filter could only drop songs ParentId legitimately returns: the #2076 singles have the album as parent, but their AlbumId field points at their own single entry.

nothing needed fixing jellyfin-side, the workaround was for a parameter this request stopped using in august.
