I gave up on automating it, I download with slskd, and run musicbrainz Picard (import slskd download folder, and set it to always save to the jellyfin music folder/rename with my preferred sorting method). This has the bonus of downloading the cover art, and rarely has issues.
I did this twice in both big toes, as the first time they only did the sides.
Now I gross out coworkers and fascinate small children when I wear sandals, and haven’t had big toenails in close to 20 years.
