Sex is more openly spoken about than 40, 50 years ago, and I think probably in comparison to a lot of bands - certainly other contemporary pop girl bands - we're certainly not as suggestive. We talk about sex in the way that we would to our friends. As a girl group, I think it was important not to avoid those sort of things either, because it's about confronting people's idea of what women should be talking about and how they should talk about it. There's no point in shying away from subjects like that, because they exist.

I find it strange that there isn't more of a melting pot of language within the pop charts. I feel it becomes really two dimensional when everything's in English.

I instinctively want to create pop songs and I think it's really good to challenge that, otherwise it becomes a habit.

Because it's my first language, all the literature that I've read and all the things that I've been inspired by that have been written in Welsh have moved me beyond anything that I've experienced in any other language.

In a world where globalisation wants to turn everybody into the same thing, I think that anything that allows you to go to another place or be in another world has got to be celebrated.

You need to push yourself, put yourself in uncomfortable situations rather than stick to your comfort zone.
