I use Jellyfin but I download all my songs from Tidal, Qobuz or Deezer and tag them automatically right then and there in a clean format so Jellyfin does not have to guess at all.

I also have some automatic checks in place to convert incorrect metadata to a proper format. Like moving artists from the title (feat. Somebody else) to the artists tag Somebody; Somebody else and a bunch more.

Together with Finamp on desktop and mobile everything is pretty much working as expected.
