In the evangelical subculture of my youth, there were three categories of pop music. There was secular music, the avoidance of which was, as with alcohol, a nonessential of the faith. (My parents’ approach was more tight regulation than outright ban.) There was Christian music, the Nashville-industry pop records that we heard on Christian radio during our school carpool and then saved our allowances up to buy. And then there was worship music, which we sang at church.
