I don't know about the commercial, but as it's in the trailer I'd say it's either;
The Dead Weather - Hang You from the Heavens or
Metric - Help I'm Alive
The song in the Vampire Diaries commercial is by the dead weather and is called "hang you from the Heavens." or "to lose my life" was also featured in the theme song/ commercial during the show.
down
its called Timebomb by Flesh =]
I'm not quite sure but it could be, from some Vampire Diaries commercials I've seen, either: No You Girls by Franz Ferdinand or (the theme song) Help I'm Alive by Metric
Cosmic Love by Florence and The Machine. It's a beautiful song.
Bury Me Alive by We Are The Fallen
"Sort Of" by Silversun Pickups - Amazing song, amazing show!
Hang You From The Heaven by The Dead Weather
Brick By Boring Brick
one republic- say (all i need)
Help I'm Alive by Metric, hope it helps :D I like it too.
