If I wasn't a musician I'd probably be like a meth addict.

I worry that if I enjoy something - like the songs on 'Some Nights' are about wondering about who you are. I'm never quite sure and I'd hate to feel sort of content and get a good sense of who I am because if I know one thing, that's not me. I don't mind not necessarily being happy about it. And that's fine.

It's important that I get time to run, to just go for a jog for about 30 minutes. It helps with my voice, but it also kind of gives me a little bit of time to myself - and you get to see a city.

It takes a lot to still believe in people.

I would love to play a show with Kanye West. That would be amazing. I want to play a show with Tom Petty or Bruce Springsteen. It would be really fun, especially to stick around, watch their show and watch how they work a crowd. It's really a wonderful thing.

I tried to play bass in a punk band once, and it was an absolute disaster. I can’t play anything. I don’t know what it is.

It's as simple as finding something on the street and then writing a jingle. If I'm driving and I have my turn signal on and it's rhythmic, maybe I just write a song to that.
