You can't be in a bubble being a producer. You have to keep up on what's happening at all times.

I'm listening to Spotify all the time and pulling in different things. I might find an artist or a song that I like, and I'll pull that into playlists, and then you'll find related artists. But I like an album as a nostalgic thing; I remember buying albums and getting into the whole thing.

I'm still waiting for rock bands to come back, something raw and relevant.

Sia is like no one else I've ever worked with. She comes completely from this non-logical but very emotional place. I could be wrong, but she doesn't really seem to analyse what she's writing. She doesn't really revise it, but goes with that first thing that comes out.

There's a lot of songs and songwriters out there - you have to make something stand out to pitch songs. Sometimes you have to be bold and just try something different. And just stick with it - don't give up if nothing happens.

I left my band on my own, and it took me a long time to find major success again - almost a decade. And everything that didn't happen during that time just motivated me to do better.
