I just picked it because I know Stephanie thinks so.

But I love Muse ^^

Kelly Clarkson has sooooo many good songs for these books! seriously, like more than half the ones on all three of her albums are perfect for Twilight New Moon or Eclipse.

a lot of their songs from "Hybrid Theory" remind me of Twilight, new moon, and eclipse...

Within Temptation - because it first has a strong sound but soft yet powerful as a lullabye.

songs - for example -
"Blue Eyes", "Mother Earth", and "The Howling" describes Twilight
"Bittersweet", "Angels", and "Memories" describe New Moon as a whole, not just little parts
"Dangerous Mind" and "Our Solemn Hour" describes Eclipse

and the band as a whole is perfect representives of all the characters in the books!

I think Flyleaf is pretty good for the books! I like all of these bands but I think Flyleaf is the best!=)
Songs-
"Fully Alive", "Perfect', "There for you", "So I thought"
"Sorrow","I'm Sorry", "All Around Me", "Red Sam", "There for you", "So I thought"
"Sorrow", "There for you", "So I thought"

Also, Within Temptation has The Truth Beneath the Rose which fits when Bella thought Jacob was killing people.

I think Muse would be the best fit for all the above reasons lol :D

Um, well, I've only listened to two of the people listed, so I'm probably not well inforemed. Who is Muse? but actually Kelly Clarkson has a bunch of great songs too.

Evanescene's Everybody's Fool really descibes a vampires life. kinda
