I think Justin Bieber played a couple of songs up the block from it - and they said that some-one in his camp came and got him a burger. We had been talking about him a lot. Especially actually, last time we came to Australia, C.T. was on a real big Justin Bieber kick. I just thought it was really interesting to finally cross paths with him in New Zealand. And like really - the TV, everyone's just talking about it on the radio - it's a big deal that he was here. I think he just left.

It was more just about serving the song, which is sort of the way that we work in general. We wanna do the best that we can with it and make it the most interesting to our ears. And putting auto-tune on 'California English', was just one reflection of that.

I think in general, it's just an interesting age to be at, after college. You spend so much of your life, being on this academic trajectory - and then when it's done - all of a sudden the whole world is maybe open to you. But you're the one that's really in charge of your path. And that can be a really scary thing, I think.

When you're working on a record, I find it's better not to share details during that process. Because, until it's done, it can change.

Maybe it's just a humanising thing to realise that a ton of people in bands that make really exciting music, are just big nerds. And you know, maybe the Internet's done a lot in just exposing that long-held secret.

I remember being like, 12 years old, and this was in the days before cell phones, or at least, having a cell phone. Some girls, I can't even remember who they said they were, called and said they had a crush on me. But it turned out to be a prank, and I thought that was just straight up nasty, you know what I'm saying? You're just sort of developing. You're insecure, your bones are growing... you have trouble sleeping. And all of a sudden, someone's pranking you on top of that? It's tough growing up.

I definitely have friends who - they've gone to multiple jobs, they've had trouble finding jobs, some have gone back to school - it's a very transitional period in anyone's life. I think definitely people have, even like my girlfriend for example, she works her job - and just the fact that she has a job - she just feels super lucky in this economy. But it can really shape, I think, the way you view the world.
