For those of you that have somehow mercifully escaped being exposed to Ke$ha up until this point, here's a simple thought exercise: imagine if Lady Gaga had to start her act again from scratch, but instead of millions of dollars to spend on production design, songwriting and wardrobe, she only had $125 and a handful of food stamps? Obviously, the first thing you'd do is shortchange the songwriting budget, which explains why "Tik Tok" makes "Poker Face" sound like Beethoven's Ninth.
