I think I have just died and gone to librarian heaven. In the video for Cascada’s “Everytime We Touch” (debut album is in stores now), the sexy siren rescues a Josh Hartnett lookalike from behind the reference desk as his staid surroundings turn into a bangin’ nightclub. True, the song is pretty generic, of the thump-thump beat-beat variety, but it’s still catchy as hell. And — hello! — she’s dancing atop a card catalog! Total bibliophile porn.
