Commercial Breaks & Beats

Does anyone know what the music was for the Ted Bundy program trailer on Channel 4? It was an instrumental bit of music in the GSYBE or Mogwai type vein and was really familiar - it is driving me mad as I can't place it.

It's either The Downward Spiral or Hurt by Nine Inch Nails on the Downward Spiral album. A good album if I may say.
