When Ke$ha tries to rap like L'Trimm, she sounds like any ordinary lonely teenage girl stuck in a nowhere town, singing along to her radio and dreaming of a party where she's the star. Ke$ha's greatness is that in her voice, you can hear both the loser girl and the star. All hail the Queen of Noi$e!
In the old days, when a star left a still-thriving hit show, they'd celebrate by killing him or her off. But 'The Office' dispatched Michael Scott in a crueler and more final way: they made him normal. Since we're talking about Michael Scott, 'normal' might be stretching it, obviously.
In their heyday, the Pet Shop Boys were the Interpol of the Eighties, dressing up to sing really weird pop songs about lust and loneliness in the big city. They're low-pro now, not retro-worshipped in the manner of Depeche Mode, New Order, or The Cure, but you can hear the reason why - these guys are too sad.
