I heart all three of the Twilight Saga Soundtracks (and I don't even care if you make fun of me about it).
The New Moon Soundtrack is a bit more up beat and adds in a folky-twist that is auditorily stimulating. I knew I'd like New Moon soundtrack when I found out Death Cab for Cutie and The Killers were on there. They didn't disappoint! And I love the Sea Wolf's and Hurricane Bells' songs too.
I know what you are thinking. She likes Twilight stuff so obviously she likes the music but it's more than that. Even Matt likes these soundtracks (and he'd rather scrub toilets with his own toothbrush than have anything to do with the books/movies). Yep, they are that good.
Are you glad I just lay this random stuff out for you?
