I always seem to feel that everything is about to cave in on me. I think that maybe music is my protection from that and in some senses it's an outlet to turn it into something euphoric: embracing the eventual decline.

Love is horrible. I mean, when you're in love, it's like a sickness. Such madness.

Being heartbroken is like having this really horrible freedom. You can be selfish with your thoughts, which can lead to manic creativity, but at the same time you're just really miserable.

I've been thinking about songwriting more in terms of playing it live, and how it will sound as a band.

I'm one of those people that is up for most things. When I was offered to sing at the Oscars I was like, 'Yeah, I want to know what that's like!' I'm always curious to know what things are like - as long as you're not compromising who you are.

Bono told me how to dance in high heels and he also told me about U2's Glastonbury performance and how everything that could have possibly gone wrong went wrong, including him ripping his trousers on stage. I think he was lunging and his trousers ripped! He was telling me how he had to find a new way of performing that didn't involve moving.

I can’t worry too much about the everyday things. Otherwise I’d lose touch with my own world, that helps me as an artist, but it’s frustrating for the people around me. I’m vaguely functional, but there’s always something slightly off.
