Yes, it was used. The trailer was sort of split into two halves for songs, and they used 30 Seconds to Mars as well as Jónsi.

For the teaser coming our way soon, I reckon they'll use an instrumental track not from the movie's actual score. I'm curious to see what it'll be. 8D ...although, to be real, my thoughts will probably only be for what my eyes are seeing the first time around.
