When I was young, my voice was so strong, and I would annoy people because I had such a loud little voice. And then it changed, and I thought I wouldn't be able to sing again, because I thought you had to sing like Christina Aguilera to be a singer.

My mom was a folk singer and Celtic harpist. My dad was in a barbershop quartet and my great grandma was an opera singer. As I grew up, I discovered pop music and Top 40 radio, but it was in the '90s, so music was very different then - it was really lyrical.

I never really focus on writing for other people, to be honest. Every song I've ever written was for me to sing. Maybe if I'm writing for a rapper, but I'd still write it as though it was for myself and then sometimes I'm actually asked to do the part.

I have a tattoo on my foot that says 'it's a whale' in Japanese, because Japanese people kill whales. My stuffed whale was like most children's teddy bear. I took it with me everywhere. I slept with it. I couldn't live without my whale.

I think one of the reasons I've had success in hip-hop is that I can bring out vulnerability in people who are generally seen as tough guys. To me, when a hip-hop musician always plays tough, I find it annoying because I know they're not really like that - there's something deeper and vulnerable. There has to be, because they're human beings.

I'm not a big fan of trying to be a sex symbol or any of that stuff because I really like the music to speak for itself.
