Death Cab for Cutie...

is the music they play in trailers when they want guys to feel an emotional connection to the film.
"Hey, that trailer is playing "The New Year". I understand that the lead male character is feeling the exact manly emotions that I'm afraid to let anyone know feel. I must see this movie."

When they want women to feel an emotional connection in a trailer they play Michelle Branch or James Blunt. (luckily, I'm immune to that sort of musical tactic)
