I think the true test of a pop song, for me, and I've talked to a lot of other writers about this, is you take your demo, you pop it in your car and you drive down Sunset Blvd. to Santa Monica, and that's the Hollywood car test.

I live in Los Angeles, which is the second most polluted city in the world, and I wake up in the morning to dirt all over my window.

I'm a sucker for pop melodies, things you can't get out of your head.

I started selling corn dogs, ended up in the music industry. That's how it all started.

I'm terribly forgetful. I've lost laptops, cell-phones.

I find the songs that have the most human components in production are the ones that will stand the test of time.

When you're around enormously successful people you realise their success isn't an accident - it's about work.
