It took time to really build myself a reputation as a good live performer, a musician and an artist.

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.

Drake, I'd like to collaborate with. He's a phenomenal lyricist. Probably the best rapper in the world at the moment. I love Kanye but there's something about Drake; he's more straight up, really clever and really poetic and metaphorical - I love that. He's just clever.

I feel like sometimes I'm so positive and sometimes I think the worst of everything or I think the worst is going to happen. It's how I deal with stuff day-to-day, it's just how I get by really, and it's probably not the best way to be.

'I Know You Care' is about my dad. And I haven't seen him for a long, long time. And my parents divorced when I was really young. And I guess I just wanted a - it was my way of saying that I wasn't bitter or angry anymore. I was just sad and just felt like something was missing.

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.

I'd call what I do pop music, but it's folky and electronic and it doesn't really sound like much else.
