'''''The Definitive Nine Inch Nails''''' (usually referred to as '''''The Definitive NIN''''') is a four-part collection of [[Nine Inch Nails]]' greatest hits. The first three parts were originally released as a three-disc collection via BitTorrent.
These were later expanded and a fourth part was added via the nin:access iPhone app and the "Listen" section of [[nin.com]]. They were again modified each time as they were posted on the [http://soundcloud.com/nineinchnails official NIN SoundCloud account], [http://open.spotify.com/user/treznor Trent Reznor's official Spotify account] and the [http://on.beatsmusic.com/artists/ar24468 official NIN Beats Musicaccount].
The collection amasses over 100 NIN songs across its various iterations, and ''Quiet Tracks'' also contains tracks from [[Trent Reznor]] and [[Atticus Ross]]' scores for ''[[The Social Network Soundtrack|The Social Network]]'' and ''[[The Girl With The Dragon Tattoo Soundtrack|The Girl With The Dragon Tattoo]]''.
