The song in the beginning is called Fader
dream by the pied pipers (Added) This is the actual song. Dreams by Pied Pipers is technically the song but in the teaser trailer it is different. Here is the remastered version. Made the video myself :] http://www.youtube.com/watch?v=9WrMw77hCqU&feature=channel_video_title
The creepy piano song in the background , "I've Got No Strings" from Pinocchio.
The one where the are driving into hell is called Fader by The Temper Trap
It's Kissing You by Des'ree- off from the Romeo and Juliet Soundtrack Sorry to say but after research of my own I found that it's not the song listed above. I do like the Romeo and Juliet soundtrack though. There are two songs in the new teaser trailer of Breaking Dawn... Love and Loss- Two Steps from Hell Infinite Legends- Two Steps from Hell This also happens to be the same performer of the same type of music in the trailer for the previous film! Good luck and mp32video is a good website to get youtube stuff :)
