Obviously I got known for some other songs early on, and some of those were rock'n'roll songs. Some of them were melodic pop songs. And I've done lots of different things, as you know, but every so often I get drawn back.
I think when I was younger I was not very good at writing love songs that didn't have a twist.
I get very frustrated by this term 'genre exercise.' I mean, what exactly is that? Genre is not really relevant when you are writing a song; hopefully you are doing it to explore something, to create something, and I don't agree that any of my albums are genre exercises.
I've always felt writing a song was a bit like going on location. That's true in an almost literal sense. Where you are seeps in somehow.
It's what I do. I don't deserve any awards for this, it's just music. It's just writing songs. You sit down, you write a song, you record it. You tour and play the songs live, dress them up a bit differently, or dress them down.
I'd be very suspicious of anybody that seems to have to move to the next level of expression. I distrust that: now I'm writing a book, now I'm being an actor. It should be a natural thing. I think it's a natural thing for you to act. But I think that people that feel that, because they've written one maybe quite beautiful love song that equips them to play Romeo, is probably misguided.
Certain songs have been written years apart, but they have a natural continuity to my mind.
It's not crazy to want to have certain songs be developed harmonically and still want to make noise with the guitar. And you can have both.
Smokey Robinson writes the heartfelt songs, whereas it was my job to write the songs about weakness and failure in love.
I saw you dancing out the ocean Running fast along the sand A spirit born of earth and water Fire flying from your hands
I've reached the stage of my life where learning is so important to me. I go through the past enough when I play my old songs on stage. And I don't mind doing that. But I want to think about the future.
I can't think of anything until I've got printed words in front of me. I never wake up in the middle of the night with a song in my head.
I don't have to compete in the charts. I can just be myself as a musician, a songwriter and play with the musicians that I really love.
It's so easy to write songs about misery and hard times and sadness. It's much more difficult to write songs about happy and chirpy stuff.
I think going away and disappearing for a couple of years - or a few years, or whatever - definitely changed the way I look at songwriting. It made me feel more free, it made me feel more like I could just write what I wanted to write about. I wanted to write more observational songs.
I've been doing four-track songs by myself since I was like a teenager, where I'd sing in a way that I ... I just didn't think other people would like it, so I didn't play it for them but eventually I got over that, which I'm happy that I did, because it's kind of a drag to be playing a kind of music that you don't really like as much as another kind.
You can take a picture of New York and one person looking at it will think it looks really depressing, frightening; and someone else will look at it and think of all the fun things you can do in New York. I think songs are kinda like that.
I think people always have - not just journalists who help their careers, I think all people struggle with this idea that a female pop artist can write all her songs. Even I do it sometimes, you see a really good female pop artist and you're like, 'I wonder if she writes her songs.' That's never really my first initial reaction to a male popstar.
When I'm writing obviously I have all the nostalgia in the world, I have all the emotion in the world, but then when I actually perform, I need to just perform it, and that's it. I do retain like a little bit of it because I have to, I sing and perform the songs so I have to - it's a performance of the songs - but I just have to get the right balance.
I wrote 'Lights' a long, long time ago. And I expected it to be on the album, because it was - I wrote it with 'Biff' Stannard. And he wrote every single Spice Girls song and every single pop song of the 90s, basically. So I thought, you know, I was really lucky to work with him, but I didn't think it would be a big song for some reason.
Some people don't have a way of that catharsis and I do, so I'm lucky in that sense that people listen to my songs and enjoy my songs. It's a really important thing for me, it's how I channel everything. I don't really know what I'd do if I didn't write songs.
I met Prince William at a musical festival and he let me know he was a fan of my music. But the invitation to sing at his wedding reception came completely out of the blue. The fact that Kate and William knew the words to my songs was very touching.
Two things I'm obsessed with are the countryside and fields and being in the open space and body parts, so you'll hear me mentioning body parts and human anatomy. I've listened to my songs and I think I am quite visual and I talk about bones and flesh a lot.
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.
You pick up loads of baggage with your first record with reaction to it from fans and critics. So I went to Ireland by myself for a couple of weeks with my guitar. I read lots of poetry, I read Patti Smith's autobiography and started words and phrases and then songs started to take shape.
