THR: How did you come to work with Miley Cyrus.
Williams: I would see her from time to time. I have this theory about Disney artists: They have the best work ethic ever. She had inquired about working with me, but I had inquired about looking for her—we found each other at the same time.
THR: What is it like working with someone who comes from such a song factory?
Williams: We talked a lot before we did anything. She’s very clear on what she wants to do. She’s not confused at all. And she hears a hit like a baseball coming off a bat. She gets it. People are like, “Really?” And I’m like, “Yeah!” I remember when they said that to me about Britney. I remember when they asked me, “Why Justin?” I was like, “Because there is a guy in that group you think you know—but you really don’t.
THR: What will the album sound like?
Williams: She sang me a song—her voice is totally different from the “Party in the U.S.A.” thing. There’s way more country influence. That should be obvious, but most people don’t know that. There’s definitely a lot of hip hop at the heart of it. I don’t want to give too much away, but her project is a definitely a melting pot of all the stuff she likes.
