Not really meant for self hosting, but have you looked at listenbrainz? The software and data is open and it’s not a commercial service.

For clarity, I’m assuming you meant “accused” or “tried” rather than “convicted.”

That makes sense, personally I would consider nonbeliever to be only people who don’t follow any religion, but I can see how it is more up to interpretation.

I understand that, but if someone says they are “Jewish by birth and nonbeliever by belief,” I would think they would be in the ethnic group but not the religion, as opposed to someone who does also practice the religion.

Wouldn’t that be an ethnicity then, and not a religious identity?
