I can't wait for this movie. I liked the Swedish original and I liked the original noir novel. I can't wait for the soundtrack either, by Trent Reznor and Atticus Ross. Now you can download six tracks for free.
Unfortunately, none of them is the angry cover of Led Zeppelin's Immigrant Song used in the teaser trailer. You can buy that song in iTunes now, however.
The good news: I listened to them and they are excellent. [NullCo]
