Here are a list of songs that i think go good with twilight...
*My wish-Rascal Flatts
*A Moment Like This
*Better Than Me- Hinder
*Forever-Papa Roach

And this one is special for Jacob
*What Hurts The Most- Rascal Flatts...for like the end of Eclipse or now that i think about it it could be for the part were Edward leaves her in New Moon...

Those are a couple of songs i think would be good ones...if you know anymore leave them as a comment
