I wonder if there's a way that you can talk to the pastor about having one hymn or gospel song in each service where everyone turns around and faces you and sings?

In the Friday night service, during "Lecha Dodi" (where the Sabbath is welcomed as a Bride) everyone turns to face the doors, sometimes beckoning with their hands, to physically welcome the Sabbath's entry into the community. That's what I see when I think about your congregation perhaps physically welcoming the joy of your music into their worship.
