This shows how little the author was paying attention and the astounding chasm of ignorance she demonstrated with respect to Christianity. At least four in a row of Cook's songs were songs that are heavy on religious undertones. One group is an explicitly Christian group (Switchfoot). Two of the others have huge Christian followings because of the very recognizably christian messages of their songs (U2, Collective Soul). The fourth song I didn't recognize, but it seemed to have some lyrics about faith.
