When I wrote 'When the Party's Over,' it had a universal quality.
Everything sounds better when Billie sings it, so the only ones I'll keep for myself are ones that really feel just super personal to me in their content, like this is my life story and maybe not anybody else's.
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.
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.
I love pop songs so much and I don't put a ton of pressure on myself as a solo artist to always write the most commercial feeling thing, I just want to write things I would love to listen to.
If I'm making a song with Billie, then it's for Billie... She has to want to wear that song every day. And I think I try to do the same thing when I'm making a song for myself... I try to treat them both that way, like I'm sort of A&R-ing her and then A&R-ing myself.
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.
Love has always been the most important thing to me and the thing by which my life is guided.
It's important to recognize when a song remains important to you.
I don't really have any interest in recording at places that are institutionalized for recording.
