I don’t use pinchflat or jellyfin for just audio but my organization is /shows/{{ source\_custom\_name }}/{{ upload\_year }}/{{ upload\_yyyy\_mm\_dd }} {{ title }}/{{ title }} \[{{ id }}].{{ ext }}

Or for better visibility /shows/channel_name/upload_year/upload_date + title/title

Again I don’t use it for music so I’m using it like TV
