Reznor said that after he heard Cash’s version that the song now belongs to Cash.
I actually enjoyed NIN back in the nineties, and would even play Reznor’s original and Cash’s cover back to back whenever I was bombed in a bar, which was quite frequent at one point in my life. The one comes off more than a little nihilist, abandon all hope all ye who enter here, burn it all down. The other, well, it was real, all too real, and heartfelt. It was his swan song.
