I think Ray Charles did as much as anybody when he did his country music album. Ray Charles broke down borders and showed the similarities between country music and R&B.

I've always said that Adele has turned so many people on to British singers - whether female singers or just like music from this country in general.

We used to play music for fun. Much more than now. Now nobody picks up a guitar unless they're paid for it.

I'm obsessed with the countryside: woods, forests, fields, lakes, mountains. I'm really into folk music and folklore. But more so I'm into electronic music. I'm into bands that have both aspects, like Boards of Canada is a perfect example. You could listen to that type of music running through a woods. It's kind of what I wanted to achieve.

I need music. It's like my heartbeat, so to speak. It keeps me going no matter what's going on - bad games, press, whatever!

I don't really have a style icon but I really admire the way people dress like Gaga, Rihanna and Gwen Stefani. It's good to be inspired by singers who write music and dress incredibly - rather than models and people in the fashion industry who dress immaculately anyway because it's their style.

It is so characteristic, that just when the mechanics of reproduction are so vastly improved, there are fewer and fewer people who know how the music should be played.

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.

Pop changes week to week, month to month. But great music is like literature.

I started getting these attacks in 2009, just as my music career was taking off. I'd be doing photo-shoots and started to feel like I was having heart attacks. Increasingly I found it difficult to step outside my flat. Things started to get better after I saw a therapist, who told me I needed to make peace with my panic attacks.
