Lifted from Wikipedia:
When Reznor was asked if Cash could cover his song, Reznor said he was "flattered" but worried that "the idea sounded a bit gimmicky." He became a fan of Cash's version, however, once he saw the music video.
"A few weeks later, a CD shows up with the track. Again, I'm in the middle of something and put it on and give it a cursory listen. It sounded... weird to me. That song in particular was straight from my soul, and it felt very strange hearing the highly identifiable voice of Johnny Cash singing it. It was a good version, and I certainly wasn't cringing or anything, but it felt like I was watching my girlfriend fuck somebody else. Or something like that. Anyway, a few weeks later, a videotape shows up with Mark Romanek's video on it. It's morning; I'm in the studio in New Orleans working on Zack De La Rocha's record with him; I pop the video in, and... wow. Tears welling, silence, goose-bumps... Wow. I just lost my girlfriend, because that song isn't mine any more. Then it all made sense to me. 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. Some-fucking-how 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. Things felt even stranger when he passed away. The song's purpose shifted again. It's incredibly flattering as a writer to have your song chosen by someone who's a great writer and a great artist."
