Promo? I remember her revealing the album cover on screens all across North America in urban areas with her album title plastered all over them. It probably costed her team millions.

Lord knows I dislike Katy, but "Walking on Air" (As low of a replay factor it has) and "Dark Horse" are miles better than "Applause". I actually think I might like 'PRISM'.
