Forget Lea Michele or Matthew Morrison. Glee's real breakout stars are the Warblers. What's not to love? The glee choir from Kurt's new school is like a massive, beat-boxing boy band in prep school uniforms. That absolutely kills any song ever by a female diva. (Honestly, Katy Perry and Pink, just give up. The Warblers do it better.) Their "Do Ya Think I'm Sexy" sounds like it was (brilliantly) filtered through "SexyBack." Their "Blackbird" packs a serious gut-punch of pathos. And their all a cappella "Bills, Bills, Bills" is half as fierce as the original -- and that's a serious compliment.
