A good choir can send chills up your spine. And in recent years, choirs have really broken out of their traditionally religious mold -- like the Scala & Kolacny Brother’s choir from Belgium, which has become world renowned for their covers of pop and rock songs like Radiohead’s “Creep” and Kings of Leon’s “Use Somebody.”

But what about when rock and pop artists are the ones leading the choir? We asked New Yorker editor Ben Greenman and author and music writer Sean Manning to join us for a Soundcheck Smackdown.

So, What do you think. Are choirs in rock songs heavenly… or hellish?
