Things go in circles.

I have periods when I'm hungry for something new. I'm quite hungry right now. And then I have periods when I'm more domestic. I kind of make fun of my hunger on the new album in a track called Wanderlust. It's about the state of looking for something and almost knowing you're never going to find it.

Things go in circles. Wanderlust, for example, is a sort of continuity of 'Hyperballad'.
