Lyric discussion by ya_nobhead 

Nine Inch Nails wrote this song about drugs. simple as. Cash turned it into a kinda curtain call for himself. the video is properly heart wrenchign stuff.

No they didn't write this song about drugs idiot. It was written by Trent to help him get over a breakup. It isn't about drugs it's about a break up.

Reznor said: "I pop the video in, and wow… Tears welling, silence, goose-bumps… Wow. [I felt like] I just lost my girlfriend, because that song isn't mine anymore… It really made me think about how powerful music is as a medium and art form. I wrote some words and music in my bedroom as a way of staying sane, about a bleak and desperate place I was in, totally isolated and alone. [Somehow] that winds up reinterpreted by a music legend from a radically different era/genre and still retains sincerity and meaning – different, but every bit as pure."...
