Hang on, I'm a NIN fan and I totally rate the Cash version of Hurt. Because Trent sounds like a whiney little snit when he goes on about his empire of dirt. Cash, there's time and pain and love and loss going back decades and it comes out in the breaks in his voice. Man-tears are shed.
On which note, we've done Marilyn Manson's Tainted Love, yes? Takes the sterility of the original and just turns it to pure snarling poison. Delicious.
