Music is an extraordinary vehicle for expressing emotion - very powerful emotions. That's what draws millions of people towards it. And, um, I found myself always going for these darker places and - people identify with that.

As you get older, there will be a new challenge arising. What you thought you'd accomplished once, maybe the goal post has shifted and it's not what you're pursuing anymore, because you're not interested in that anymore, you know?

I only want to make music because I have a passion for it.

I have a reputation for being cold and aloof, but I'm so not that woman. I'm passionate. I love my girls, being with my girlfriends, getting involved with issues that affect other women and children who are suffering.

I love to make music and stay grounded.

We all fight over what the label 'feminism' means but for me it's about empowerment. It's not about being more powerful than men - it's about having equal rights with protection, support, justice. It's about very basic things. It's not a badge like a fashion item.

I think Scotland could take a stand in a wonderful way, ecologically and morally and ethically.
