Interesting, but he takes things a bit far, and sounds too much like lefty complaints of "cultural appropriation.' He tries to get way too much mileage out of the fact that people don't like a film reboot that hasn't even hit theaters yet. Also, for Christians who've grown up listening to rock, rap, etc; why wouldn't he expect them to use those forms of music? It's not as if American, Christian musicians grow up listening to Bach and Purcell, and then decide, hey, let's appropriate pop music! No, the Christians' musical tastes are shaped by their culture, and they're just making the music they understand. A lot of it is bad, but so is a lot of the non-Christian pop. Would sub-par musicians have done better by writing motets and masses? I suspect not. It certainly wouldn't be less parasitic. But what about Christian musicians like Michael Card, or the late Rich Mullins, that made great Christian music of the singer-songwriter/folk persuasion? The author's model doesn't explain that.
