For many fans, The Downward Spiral is the seminal Nine Inch Nails album. For me, it's The Fragile. Taken as a complete piece of work rather than individual songs, there's a flow to the music that makes this one hell of an experience.
This track in particular stands out to me. The emotion and imagery it conjures up is amazing, and the hard, jarring silence at the end is the perfect endcap. Give this one a listen; try the whole album as well...it's a fantastic audio tour through some of Trent's darker days. Be on the lookout for the new album, Hesitation Marks, available now. Also watch for the supporting 'Tension 2013' North American tour, coming to a city near you.
