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.

“Everyday People”

"Everyday People" managed to trailblaze in two different ways -- it was one of the first pop hits to deal with the subject of racial harmony, and it utilized Larry Graham's "slap" technique on the bass guitar, which would soon be copied by countless other bassists. Graham once said about his pulsating style, "I'd never done that before … that's where the freedom of creativity came in for the band, that we'd be allowed to do that." In 1978, the song's line "Different strokes for different folks" would be borrowed for the title of the hit television show Diff'rent Strokes.
