As a songwriter I hate this whole, 'If it's a sad song, it has to sound like a sad song thing.' And that goes all the way back to my days with the Format. I'm an insane narcissist, so if I have to get something off my chest, I'll get something off my chest.

But as long as you're creating the art you want to create, if people start liking you, you shouldn't have to apologize. You want your stuff to be heard by as many people as possible.

My girlfriend is a fashion designer. She has her own company called Rachel Antonoff. She is doing a collaboration with Urban Outfitters right now, a shoe collaboration with Bass. She sells to Barneys, stuff like that.

I knew how touring was for 10 years, but it's completely different now that things are popping off.

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.

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 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.
