When I sing, it's the most solitary state: just me, and the microphone, and the holy spirit. It's not about notes or scales, it's all about emotion.

My kids really are my center. They create a beautiful chaos. It's always a nice chaos with them.

Generally I don't listen to sad songs if I'm sad. I listen to happy songs.

I suppose the biggest change to me is this kind of very oversexualizing of everything. Not that anyone wants to take the sex out of rock 'n' roll, you know - that would be ludicrous - but it seems that everything now, it's like the sexuality is the only voice; everything else is gone.

To say what you feel is to dig your own grave.

This is how you know religion is failing because people think you're bonkers if you believe in God and also because it's so uncool believing in Jesus and everything.

The music business is a place where the artists are all treated like we're working for the people who are working for us. That can obviously be exaggerated when you're a female.
