Robinson is an overthinker, so perhaps it's slightly ironic that the song putting her on the map is about dancing without a single care in the world. Nothing to Regret, a pure earworm featuring a joyous, sugar-rush chorus, is pushing 60 million streams worldwide, but Robinson (first name Anna) is still learning how to let that sink in.
"Being an anxious person, it doesn't just go away," she says. "I feel like for a lot of people it just gets worse, because they've suddenly got this expectation, and then you think, 'If I get one more thing, I won't be anxious anymore'.
"Caring about your art and wanting people to like what you do is an expected part of creating things and putting them out into the world, but I think there comes a point where you just have to kind of let it be what it will be and do what you're doing and trust that process, because you drive yourself crazy otherwise."
Previously, Robinson's self-described "pedantic" focus on her songwriting held her back from believing in her work – she'd scrap a song before it was even finished. "Now I sit down and I just finish it. I finish it and I send it away," says the singer, originally from Nelson. "Sometimes when you're writing you lose the ability to know what's good and bad anymore because you're writing so much stuff. It's important to not worry if something's bad – that's okay. There's going to be lots of good stuff too."
It's certainly hard to argue with 60 million streams, and every day Robinson, 22, is surprised by Nothing to Regret's impact. She once had an entire Contiki tour tell her she'd provided the soundtrack to their overseas experience.
