Nine Inch Nails - Unused DooM 3 Alpha Track

The unused track from DooM 3 Alpha by Nine Inch Nails (Trent Reznor), presumably the original theme song. This originally appeared in the early builds of the game. However, it got replaced by Tweaker's theme in the retail version. The said track, however, fits very well in the game's atmosphere and it sounds like a darker version of “Ripe (With Decay)“ from The Fragile album.
