It's usually a big kind of vent of frustration or anger or sadness that puts me in the right frame of mind to write. It's such a cliche to say that artists write when they're down, but it's true for me. It's a relief to get out what's eating away at my heart or my soul or my head.

When I sing along with Britney Spears I will sing in an American accent. But eventually I found my own voice. My songs are so brutally honest, it would be alien to sing in any accent other than my own. Don't get me wrong - I can imitate singers. I can do bar mitzvahs and weddings.

I maintain that when I finally retire from my career in music, I will go and live back in Wales - when I am an old person, if I live to be an old person. The water I miss, and the air, there's something different about it. And I miss the simple life.

I record stuff all the time, like little vocal things. I write random things down... Sometimes I just get things stuck in my head and I record them, and that actually becomes a song quite a lot of the time.

I love designer stuff but like it will only be like, on a whim. I love Alexander Wang so much, but it's expensive.

I used to be obsessed with Pearl Jam, but I love having pink hair and kind of looking like a Barbie.

By the time I got writing 'Halcyon,' I was on a roll, and I realized I had so much to write about, I realized I had so much built up inside that I couldn't really alleviate before, and then all of a sudden it was like reservoir burst.
