New York singer-songwriter Grace VanderWaal first gained attention after appearing on America’s Got Talent in 2016. Her performance helped her score a hit with “I Don’t Know My Name,” and she signed to Simon Cowell’s label soon after. Back in June, VanderWaal dropped “Moonlight” as the lead single for her upcoming album Just the Beginning, which drops tomorrow. The song is about dealing with depression and looking back on how it’s possible for someone to change so much.

“‘Moonlight’ is a specific story,” she tells Genius. “I knew someone struggling with mental health. At the time it was still going on. Now it’s all gucci, it’s all good. When someone’s going through that, they’re not them anymore, they lose that spark. Things like that don’t go away. It only escalates. Watching that, it’s so hard to watch that. I liked to try and put that in the song.”

Grace VanderWaal recently sat down with Genius for the latest episode of Verified and broke down her track. Watch her go line-for-line with “Moonlight” in the video above, and check out past episodes, too.
