Dose has a great interview up with Alexandra Patsavas, the guru who has put together each of the Twilight soundtracks.
“Only the most try-hard of Twihards remember the exact rules of vampire baseball. But you might recall hearing Muse’s “Supermassive Black Hole” as the Cullen family stepped up to the plate in the first installment of the Twilight Saga. But then, maybe that’s not your favourite Twilight musical moment (scenes involving goofy baseball shirts so infrequently are). Maybe you’re more into swooning along to Iron & Wine’s “Flightless Bird” as Edward (Robert Pattinson) and Bella (Kristen Stewart) slow-dance at their school prom (Twilight). Or gasping over Bella’s near-death visions of Edward as Grizzly Bear’s “Slow Life” burbles up from the watery depths (New Moon). Whatever your favourite Twilight track is, though, Alexandra Patsavas had a part in it.”
