"She's back really soon and I think it's interesting 'cause when your girlfriend is an insanely talented, real musician who writes her own music, it's scary to write an album around her. And she was with me when I was kind of in the studio doing it. I realized the trick is like, show her the really rough demo version from your phone that you recorded, and if she doesn't like that, she'll tell you, then don't wait to show her the mixed finished product. Because if she doesn't like it then, then you're kind of, I don't know what to say to you. I'm sorry."
