The soundtrack to season three of Grey's Anatomy is soooo Seattle Grace. You've got your Merediths, tracks like Ingrid Michaelson's "Keep Breathing" that are neurotic and full of "dark and twisty" angst, and your Christinas, which are weird, robotic and kind of soulless. PBJ's "Young Folks" is alien enough to fit that bill, whistling or no whistling. Then there's Izzy, pretty but kind of boring, like Gomez's "Moon and Sun." The best tunes, like Robert Randolph's "Ain't Nothing Wrong with That" or Feist's "Sealion," are fun and sexy, songs with a little meat on their bones. Yup, the Callies.
