Changes

In commentary tracks from the Japanese release of ''Ghosts I-IV'', Reznor explained that ambient works by Brian Eno and Aphex Twin, as well as Eno and David Byrne's ''My Life In The Bush Of Ghosts'' and ''Bone Machine'' by Tom Waits were reference points.[https://www.youtube.com/watch?v=AQ6H1onwuVY] Reznor also stated in a fan interview that the quieter sound of ''[[Still]]'' had provided some inspiration for the album.[https://www.youtube.com/watch?v=QJdMTf2RA8c]
