Didn't realise Reznor had stopped playing it for a while, after hearing the Cash version everywhere(which I love) hearing NIN play it live felt incredible, like he was reclaiming it. Also the way they play it now is awesome, they hold off the drums for a bit longer so when it happens it's beautiful... both versions are equally incredible though. I was probably just as moved by "I Hung My Head" as well though, it's got this incredible mournful quality.
