'''''The Definitive NIN - Heavy Tracks''''', is the fourth part of "[[The Definitive NIN]]", a previously three-part collection of [[Nine Inch Nails]]' greatest hits. It was released in 2009 via the nin:access iPhone app and the "Listen" section of [[nin.com]]. It is the only release of "The Definitive NIN" to not receive a [[Halo_numbers#Seeds|seed number]]and to not be torrented.
The original collection contained this info:<br>
"A compilation album featuring 23 of NIN's harder and heavier songs."
The track listing was altered when it was added in [[playlists|playlist]] form to the official NIN SoundCloud account and altered again each time as it was added to [[Trent Reznor]]'s official Spotify account and the official NIN Beats Music account (before it was absorbed by Apple Music. ) Cover art was also added to the SoundCloud version.
