When Osbourne sticks to this role, Sleeping delivers solid dance-pop numbers like the single "One Word." When she pads her part, the material becomes more interesting. She splits the refrain "secret lover boy" into three distinct parts, doing her best to make "lover" sound salacious and pronouncing "boy" in an incredulous tone. On "Don't Touch Me While I'm Sleeping," she goes vigilante on a date rapist, a tale she relates using an incongruous baby-doll delivery. "Edge of Your Atmosphere," an insanely perky ditty that borders on techno polka, proves Perry's surreal silliness isn't limited to her lyrics. Sleeping could become a camp classic, a far better fate than Shut Up's forgotten footnote status.
