The teaser is set to a cover of Led Zeppelin's "Immigrant Song" presumably by Trent Reznor and Atticus Ross, featuring Karen O on vocals. "The feel bad movie of Christmas" apparently won't be out for another six months. The Social Network score was released within a week of the debut of the movie, chances are pretty good that the score for The Girl With the Dragon Tattoo will see a similar release schedule. These 1.5 minutes are a pretty good indication that it's going to be worth the wait.
