I've always had as many powerful, creative ladies in my life as I have men, and you could probably describe some of those relationships as romantic. I think everyone's bisexual to some degree or another; it's just a question of whether or not you choose to recognise it and embrace it. Personally, I think choosing between men and women is like choosing between cake and ice cream. You'd be daft not to try both when there are so many different flavours.

Seventy per cent humidity is ideal for vocal cords.

I have written most of my melodies walking and I feel it is definitely one of the most helpful ways of sewing all of the different things in your life together and seeing the whole picture.

I miss you, but I haven't met you yet!

What we are saying is, we've got three aluminum factories, let's work with that, we cannot change that. Why not have the Icelandic people who are educated in high-tech and work already in those factories in the higher paid jobs, why not let them build little companies who are totally Icelandic with the knowledge they have? Then they get the money and it stays in the country. Then we can support the biotech companies and the food companies and all these clusters. I think that if you want to be an environmentalist in Iceland, these are the things you've got to be putting your energy into.

I'm a little nervous. Definitely. Especially coming from an album like Biophilia, which was about the universe. This is more of a traditional singer/songwriter thing. When I started writing, I fought against it. I thought it was way too boring and predictable. But most of the time, it just happens; there's nothing you can do. You have to let it be what it is.

I would like to teach music. It's weird the way they teach music in schools like Julliard these days.
