"All I Need" by Mat Kearney
- When it destroyed you: Season three, episode one
- Why it destroyed you: The first episode after season two's emotional finale (Denny dying, Izzie quitting, general sorrow) opens with Izzie lying on the bathroom floor in her ballgown, where she's been ever since Denny died. "I feel like I'm moving in slow motion," she says. "Like I'm moving in slow motion and everything around me is moving so fast and I just wanna go back to when things were normal."
