Ke$ha's main competitor rocks a mean meat dress, but can she rock a couplet like "Your little heart goes pitter-patter/I want your liver on a platter"? This EP proves Ke$ha would kick Gaga's ass in a freestyle battle. At times — rhyming "go insane" with "see them Hanes" over squishy techno on "Blow" — that's enough. Ke$ha lives and dies by the wisecrack; "Grow a Pear" suggests the word "mangina" will never work in a pop song. She can go deeper when she wants to — see "The Harold Song," a lament about sleeping in an empty bed. But that's not why we're here. It's for jams like the awesome, Dr. Luke-produced "We R Who We R." Cheekily celebrating dance-induced dumbness over a huge hook, she's the snap queen of clubland.

“Oh Sherrie”

Steve Perry's girlfriend Sherrie Swafford was actually in the studio when Perry began writing this song--his lone Top Ten hit as a solo act--with two co-writers. The trio began at midnight one night with just "Oh, Sherrie!" and "hold on, hold on." Three hours later, they had a complete song. Swafford, however, had to wait until the next day to hear it. "Sherrie actually got tired and went to bed," Perry said. She also appeared in the video, but their relationship did not hold on for long.
