For a person as obsessed with music as I am, I always hear a song in the back of my head, all the time, and that usually is my own tune. I've done that all my life.

When I write a song, I see a tunnel, and then the chorus is an open space, or the bassline is doing this shape. I see songs as a more of a geometric, spacial experience.

Football is a fertility festival. Eleven sperm trying to get into the egg. I feel sorry for the goalkeeper.

When I was a teenager in Iceland people would throw rocks and shout abuse at me because they thought I was weird. I never got that in London no matter what I wore.

Sometimes when I write lyrics there are images in them, usually on a quite simplistic level, like colors. But most often music comes first and then later I sit down with visual people and we chat about what we want to do. I don't look at myself as a visual artist. I make music.

Sometimes, when I have a lot of ideas and I want to do a lot of things, or when I'm traveling, I lose energy and I can't do as many things as I want. So I have to plan days when I'm not doing anything. I find that a bit boring, but it's necessary.

When I was 18, science, physics, and math were my favorite. I was a bit of a nerd - the only girl with a lot of boys at chess championships.
