Florence + The Machine - "Rabbit Heart (Raise It Up)" or "Dog Days Are Over" (love both of these songs)

Or, a more recent favorite for me:

Marina & The Diamonds - "Mowgli's Road" ... It's an unusual song with a good beat, and I love the chorus, "Forsaken road... there's a fork in the road... well, I don't know don't know don't know who I want to be."
