When I'm writing a pop song, I'll just write formulaically, strategically.

I really felt like 'Chandelier' was a big pop song. But we weren't sure what would happen if I wasn't willing to show my face and do promo and go on tour and do the traditional kind of pop strategy. So I had no expectations.

I'll be the songwriter for pop stars and then they can be the front person and I don't have to be famous.

Throw riches out of the window and hit me with music!

You have to learn how to act a pop song. You have to find the balance of the pop from the pop song and the lyrical significance of the scene you are in.

Creating a decent pop song is a challenge - and occasionally, once in every decade - it's kind of fun to do that.
