I think that Evanescense is a great choice for future people on the Twilight Saga's soundtracks....

I was just putting together a playlist for my mp3 player, and there were a few other bands that could be good for future soundtracks...

Hellogoodbye, Cold, Breaking Benjamin, Five Bolt Main, Finger Eleven, Sick Puppies, Godsmack, Sixx AM, My Chemical Romance, Drowning Pool, S Club 7, Three Days Grace....

Yeah...There are certain songs for different characters that I think would fit, but I think that would take too long to type.

Anyways...My Immortal. That's my fave song by them. =]
