Sometimes when you're on tour, it feels like you're living the same day over and over again.

I love that, for Kanye [West], there's no difference between the epic and the personal. That makes him sound like a really grandiose douche - which, I don't think anyone, himself included, could contest - but at the same time, it's really amazing. I love the scope of his perfectionism.

I'm the worst at favourites! I don't have one - I love all my children, I love them all equally.

When you make a melody that doesn't come with words from the get-go, sometimes you're just thinking about random vowel sounds that go with it - and it's really, really hard to write lyrics that actually obey the vowel sounds.

Clearly, things are definitely changing in big ways as far as the way we consume music, listen to music, and what we expect from music.

There's a certain power in vague language, but I started to get more into the idea of really trying to have a discrete thought in the lyrics and to have songs that were about stuff - to try to make things more coherent.

Sometimes you get really bitter about how the prettiest images don't typically end up attached to the most interesting music. But I just take that as a challenge to try to do something cool.
