===Heresy (Demo)===
This demo version is found on the 2-disc Deluxe Edition of ''The Downward Spiral.'' The vocals in the verses are solely whispered, rather than both whispered and sung in Reznor's high register as on album version. As well, the tempo is slower(105 instead of 115 BPM), and the structure is altered, featuring a differently-arranged introduction.
