Katy Perry is one of the most bankable contemporary pop singers—"Roar," the first single from her new album Prism, became her eighth No. 1 on the Billboard Hot 100 in August. Prism is expected to sell about 300,000 copies its first week in stores. It is a dreadful album, way too concerned with preserving Perry's star than using said star to push sonically. It is also dreadful because Perry has absolutely nothing to say.
