Version 2.0 of Nine Inch Nails Ambient Music Tracks. Over 5 Hours of content to enjoy (over 6 Addons + this base mod)
Many thanks to Trent Reznor for releasing all his music as creative commons in multi-tracks and allowing the creation of this
Should note due to the nature of how music is handled inside of Factorio there can be moments of prolonged silence or repeat songs (including vanilla songs) in close proximity. There is not much at this moment in time I can do to alter this as it's beyond my ability to do so.
This should also be compatible both forwards and backward. If you are using an older version just change the "info.json" file to match your current version of Factorio. This should be the norm unless Factorio changes how the ambient music is handled.
