I think any branding for me is band-related. It's really weird to get used to the exposure, because I am a naturally introverted person, and I'm not exactly social. Occasionally I can get comfortable enough to talk, but I spend a lot of my days not talking, especially when I'm at home and not on tour.

I'm not going to lie. I check the iTunes charts. It's all about the iTunes charts. I only go on the Internet for the iTunes charts and basketball blogs.

I don't play an instrument - I just write in my head, and I usually hear fully formed songs. 'We Are Young' turned out so much like it was in my head. But it also exceeded all my expectations.

If you look at a lot of the songs I've been involved in, there's always been this retro vibe. I started getting worried that I wasn't moving forward very much, nor was I even in tune with the music today. I almost scoffed at it.

If you can make the song a soundtrack to what you're living at the time, I think that's the most important part of a song.

In a city like New York, any night can be completely different, even in a subtle way.

Van Morrison is probably, at this point in time, my biggest influence as a vocalist. When we were making our last album I had a vinyl copy of 'Veedon Fleece' in the vocal booth in front of me, in the dorky sense. I think there were candles around, which is really tacky, but hey, I needed to channel Van the Man!
