The music industry has always been a beast, which would eat you up and spit you out.

In a sense, the music business and I haven't always been the best of bedfellows. Artists often have to fight their corner. Your music goes through these filters of record labels and media, and you're hoping you'll find someone who'll help you get your work into the world.

There's so much stigma around HIV/AIDS. It's a challenging issue, and the people that already have been tested and know their status find it very, very hard to disclose their status, to live with that virus, and to even seek out the kind of information they need. This experience of going to South Africa a decade ago really woke me up to the scale of the HIV/AIDS pandemic in sub-Saharan Africa, how it was affecting women and their children. I haven't been able to walk away from it.

I identify with other women because of my gender, and I identify with other women if they are mothers because I'm a mother, too. It's very simple. It's nothing complicated, it's not rocket science. It's about empathy. It's about understanding that what happens with one person is potentially what happens to you, and seeing yourself in someone else's shoes. Fundamentally, we are all in the same place: we're born, we live, and we're going to die. In between, we'll have joy and we'll have sadness.

Motherhood was the great equaliser for me; I started to identify with everybody.

Those in the developing world have so few rights - we take a lot for granted in the developed world.
