I will be very sad when global warming and toxins kill off all the toads and frogs and salamanders. Here's hoping we, as humans, figure out a way to be less stupid.

When I saw music as a means to an end - more fame, more money, dating celebrities - that's when things have gone terribly wrong. Now my life is focused on just trying to keep making music. Because when it's really good, it's just the most remarkable feeling on the planet.

Every single day the world seems like it is on the brink of falling apart. But then I look outside my window, and things look about the same as they did a week ago. It's almost a form of cognitive dissonance.

I run into a lot of people who are instantly filled with ridicule at the idea that someone wouldn't eat meat.

The young have to kill the old. The young, if they want to achieve their own platform, have to diminish the reputations of the ones that have gone before. That's how life works.

If I'm walking down the street and someone stops me and says, "Oh! A song that you wrote meant a lot to me, and I listened to it after I went to my sister's funeral," that's when it hits me.

I've worked with all sorts of random people - everybody from Metallica to Britney Spears to Ozzy Osbourne to Michael Jackson to the Beastie Boys. I've got a really strange CV. It's interesting - I work with a lot of these disparate, different people to learn what it's like to work with random people.
