There is a very palpable difference for me between some of my earlier songs and where my later work has gone. If I were making my dream set list for tonight's show, I'm probably not going to include a whole bunch of stuff from the album that I made when I was 23.

What I try to communicate is that there's a lot of crossover between that feeling of romantic heartbreak and this devastating feeling of knowing that we've punched a hole in the planet and it's spilling out oil and destroying the Gulf of Mexico and the ecosystem and seabirds and every creature.

I have a hard time really claiming my place as a songwriter or as doing anything of import really because I feel like I'm tooting my own horn in a way.

I know that a lot of songwriters write about a break up. It's a really popular topic. I think heartbreak is the number one thing people write about. I could say that's narcissistic somehow because they want everybody to admire how pained they are. But I actually do think there's something beautiful and uplifting about knowing that you're not the only one who is experiencing or has experienced that kind of devastating loss. Everyone's experienced that.

Writing a song is almost like cheating-writing because you don't have to finish your sentences, you don't have to use any punctuation, no one's going to edit your work. It's so wide open. People just grunt and that's a song. You can kind of do anything.

I just write about what comes up. Sometimes you're thinking about Palestine, and sometimes you're thinking about sex. People have a lot going on.

Sex is fun to sing about.
