The Girl With the Dragon Tattoo has already established itself as the perfect forum for Trent Reznor and Atticus Ross’s haunting, crunchy musical stylings, but the full breadth of its soundtrack is a bit of a disappointment: It’s only three full-length CDs! Damn it. That’s barely enough music to occupy me during a four-hour flight from Los Angeles to Chicago. Underachievers. Find out where you can get the soundtrack’s Karen O.-led cover of “Immigrant Song,” as well as a few clips from the new package, after the jump.Purchasing all the music online will cost you $12, and if you purchase the CDs in stores (like some sort of alien), it’ll set you back a mere $14. However, if you want one of the 3,000 signed boxed sets featuring 6 LPs, “a digital copy housed in an exclusive 8GB razor blade USB pendant,” and Reznor and Ross’s autographs, that’ll cost you $300. Splurge, I say!
