Cover art for Discipline lyrics by Nine Inch Nails

I absolutely loved With Teeth, I thought it was probably the best album Reznor could have written after quitting drugs. Ever since then I have been disappointed with Year Zero, Ghosts I-IV, and now this song. I feel he's lost his touch with his past creativity and the new music has been taking it's toll on him. I believe he kind of addresses this in this song. It sounds like he's questioning whether to get back into drugs to rejuvenate his mind (And now it's starting up, feels like I'm losing touch, nothing matters to me, nothing matters as much). Personally I would love to see him create another "The Fragile" while staying clean but I just don't see that happening. Still an amazing musician in my book nevertheless.
