It's important to recognize when a song remains important to you.

Love has always been the most important thing to me and the thing by which my life is guided.

I think we're always looking for ways to inject a sense of humor into our music.

I have nothing against reverb.

If I'm writing with or for someone else, it just has to feel true and real for them. It has to feel like they're being honest. If it's for myself, it's the same thing. It has to be something I can mean when I say it.

All my favorite songs ever are love songs. Probably topped by 'The Luckiest' by Ben Folds.

I never get tired of writing about love.

I think that's probably the number one reason why collaboration is good. You disagree with each other about things and then what we always say is whichever one of us is more passionate about the issue is the winner because if you care about something enough to fight for it, that means it's probably a good thing.

I always wanted to be on tour or making albums.

Working on TV shows was fun, but I felt crazy pressured and stressed.

I try not to shy away from specificity.

When I wrote 'When the Party's Over,' it had a universal quality.

There's always a better word than a swear word.

Imagine if somebody was like, 'Who's the next Timothee Chalamet?' It's like, he's currently Timothee Chalamet.

I have always loved Ben Folds, he's like an idol of mine, a hero of mine.

The amount of times I've been told something by artists I'm working with, which I'm sure they haven't told even their significant other or families, is shocking.

I stopped telling people what lyrics meant to them when I saw them tattoo it on them, because it clearly meant much more to them than it ever did to me.

Obviously I'm very grateful 'Bad Guy' is doing so well - it's shocking and surprising and gratifying - but I do think it's important to try to make the next song that people are gonna be excited about.

When I started, I felt that there was this incredible amount of doubt of my ability as a producer.

In the alternate reality where I wasn't involved at all, and I'd been like, just, sweating my way through, trying to have a music career for years? And then my sibling had one and I wasn't involved at all? I think I'd be very tortured by it. But the fact that we've had one in tandem makes a lot of sense.

Even though we're all together making songs and I produce them, it's so her vision. Especially when we walk out on stage every night. It's so meticulously thought through by Billie and I admire that endlessly in her.

I'm a bad guitar tuner. I have to pay somebody to tune my guitars.

If you can use songs as a tool, vehicle for empathy and a deeper understanding of how people are feeling and how people's emotions work, there's a lot of good that can come from that.

I just have no interest in being at a party.
