"Decode," which is about the relationship between Bella and Edward, will be the first single from the soundtrack; the band will shoot the video for it next month. "I chose the title 'Decode' because the song is about the building tension, awkwardness, anger and confusion between Bella and Edward," Hayley says. "Bella is the only mind Edward can't read, and I feel like that's a big part of the first book and one of the obstacles for them to overcome. It's one added tension that makes the story even better."

Well, with bands like Paramore and Muse on the Twilight soundtrack, we know the music from the movie certainly won't bite!
