The soundtrack was originally confirmed on January 7, 2011, on a ''New York Times'' panel interview with Reznor. A teaser trailer for the film was later released online on June 2nd (previously being attached to certain domestic and international films), featuring a cover of Led Zeppelin's "Immigrant Song", by Reznor, Ross and [[wp:Karen O|Karen O]] (from the Yeah Yeah Yeahs).

On August 10th, [DragonTattoo.com] (the film's official website), was updated to feature background music, with the filename "Dotcom.mp3". As was the case with "[[Hand Covers Bruise]]" from ''The Social Network'''s official site, this backing music was the first piece from the score to be available for listening.
