Reply To: Josh Groban is Jewish?

I think non-Jewish music that uplifts HaShem is most appropriate. Bava Batra 15b, Rambam, and Netanel al Fayyumi, among others, affirm the fact that G-d chooses prophets from among non-Jews. I think that dignified music without any christological references is non-problematic; the Kerakh Shel Romi says as much.
