hmm i'm really not a breaking benjamin fan but i'll take a listen!
the actual music of light up the sky sort carries the theme of it too don't you think?
so here's my other ones
screaming infidelities - dashboard confessional
way away - yellowcard
gifts and curses - yellowcard
keeper - yellowcard
fighting - yellowcard
you don't know what love is - the white stripes
run - snow patrol
who knew - pink
shimmer - fuel
stolen - dashboard confessional
question - old 97s (this one is odd because it fits when edward asks bella to marry him but it actually reminds me more of jacob)
in your arms - the last goodnight
good love - the last goodnight
mr. brightside - the killers
something inside - jonathan rhys meyers (from the August Rush soundtrack

)
swing life away - rise against
most of these relate more to jacob, but some of them can be applied to edward too. i'm actually such a loser that i not only have a twilight playlist in my iTunes, but i also have a "jake and bella" playlist.
