For "The Girl with the Dragon Tattoo"soundtrack, I think Karen O. did it again, and this time with Trent Reznor and Atticus Ross. It's so edgy and raw, and yet I feel that it still somewhat retains the feel of the original by Led Zeppelin. But what really enhances the cover, for me, has definitely got to be Karen O.'s voice. Paired with the other elements of the song, it just enhances the darkness of it all a little bit more than compared to the original. But, nonetheless, I still love this song, the original and the cover.
