“I bet if you were married in the last 20 years you came out to one of those songs too”
Bad bet to make. I have been to numerous weddings where the chosson/kallah insisted on only Jewish music and the band easily obliged them, INCLUDING for the opening dance. I don’t recall off-hand the songs used, but given the breadth of Jewish music out there, there must be (and are) options.
I feel the non-Jewish music is especially inappropriate at any seduas mitzvah, especially for a newlywed couple who are both newly tahor on their personal Yom Kippur, not to mention the rest of Klal Yisrael, so if some non-Jewish intro is played then I avoid dancing until the Jewish music starts.
