''Rolling in the Deep,'' Adele
We've all sung along with Adele in the car or the shower. But that doesn't mean anyone should even try to compare themselves to the British songstress during the Idol auditions (even though we have the sneaking suspicion the hit will be season 11's butchered song of choice). Who sings ''Rolling in the Deep''? Adele. Yeah, let's keep it that way.
