Music is a very powerful thing. If I'm angry, I can write a song about it, and it seems to make everything okay.

People don't listen to one radio station. On iTunes you can mix different worlds and bring country and pop and folk and live music together with a mass audience. I could have sung 'Easy' in a country way but I just sang it how I sing. I think it's a really nice blend.

I wanted to write about relationships. But I didn't feel I had the experience to sing about them in a deep way. Studying psychology helped me out in terms of my understanding. I still look through my old textbooks when I'm in need of inspiration.

As a teenager I had friends who had little music studios in their bedrooms and garages. I'd go and play around; very soon, my hobby became a passion.

I love arranging my music, not in alphabetical order but by mood, creating playlists for when I have energy and want to work out or go-out party mixes and music to chill out to.

My skin is like a map of where my heart has been And I can't hide the marks It's not a negative thing.

Surround yourself with friends who only call you a superstar
