Happiness in Slavery - Nine Inch Nails
I hadn't realized how wide the stereo is in this. There's a lot of out-of-phase stuff, sounds like it's coming from inside my head. Very cool that he got away with this on a commercial release (normally everything has to be mono-compatible, i.e., dull). To avoid sounding too much like an audio nerd, I'll also add that it is a kickass song.
