Well, since he is an athiest and (i'm guessing) doesn't know very much about Catholicism, he could have confused a Protestant song with a Catholic song. Also, in one of his recent comments, he said that it was more like heavy metal, which is not as common in Catholic churches. (I wouldn't know how common it is in Protestant churches)
