The music you love when you're a teenager is always going to be the most important to you.

The people you're turning to for advice are all people making Disney movies, so we had these amazing meetings where you'd see John Lasseter, and then next to him is Jen Lee, the director of Frozen. Next to her is Pete Docter, who's working on Inside Out.

It's got to feel, the pulse has to feel like this part of the world, the instrumentation has to be true to that, and so, between him, [composer] Mark Mancina and myself, we really chased that, while serving our story Moana].

It's hard to pick. I mean, I think the one that is most emblematic of the collaboration that occurred is "We Know The Way." That's the first song we wrote for the movie [Moana]. We actually got it written that weekend in New Zealand, so we're all in New Zealand, we're all absorbing this culture, and Opetaia [Foa'i] brought it in.

I still look at that water, and I look at Moana's hair, and I'm just like, "How is this even happening?" It's such an incredible mix of technical mastery and wizardry. It's really incredible. It's layers and layers and layers. It's not unlike building a musical. It's really pretty cool.

I went to a school where everyone was smarter than me. And I'm not blowin' smoke, I, my, I was surrounded by genius, genius kids. What's interesting about growing up in a culture like that is you go, "All right, I gotta figure out what my thing is. Because I'm not smarter than these kids. I'm not funnier than half of them, so I better figure out what it is I wanna do and work really hard at that because intellectually I'm treading water to, to be here."

I felt so nourished by the process of making [Moana], of you're always engaged with other artists from different disciplines, and it's about bringing your art form to the table. It's so many art forms mashed together.
