To me, rock music was never meant to be safe. I think there needs to be an element of intrigue, mystery, subversiveness. Your parents should hate it.

I lived a fairly average, anonymous small-town life till I got the idea to do Nine Inch Nails. Then I locked myself in a studio for a year, and then got off the tour bus two years after that, and I didn't know who I'd turned into.

You're standing onstage in a sold-out arena with people singing your music, and you feel like the loneliest person in the world. Because here's a party that, essentially, it's for you. And you still somehow feel like you don't belong there. Those people all have their lives and go back home.

My music has been a sort of personal therapy. It's got me out of tough times, it has been the friend that I needed, when I didn't have a friend there.

I've attended many concerts where I felt let down and I was wishing it would be something else. Not that it's their duty to please me, but at the same time, I think a lot about what it's like through the eyes of the consumer, the fan. I want not to pander to the audience, but to be aware of them.

I think the whole aspect of social networking is vulgar and repulsive in a lot of ways. But I also see why it's appealing - I've had that little high you get from posting stuff online. But then you think, 'Did I need to say that?' I've explored that enough to know to stay kind of quiet these days.
