On September 15, Grace VanderWaal released "So Much More Than This," the new single from her upcoming album, Just the Beginning. And the 13-year-old singer-songwriter is the first person who will tell you that she was nervous about the drop.

"I've been wanting people to know about this for so long and it's finally happening," she explains about her new work, which will debut in full on November 3. So it's understandable when she tells Teen Vogue she's been "refreshing" her social media feeds and "looking at people's responses and comments. It's all very positive, which I was very happy about. I was really nervous about the response."

The album follows an EP, Perfectly Imperfect, that was released shortly after she won first place on America's Got Talent. But even after a golden buzzer and Simon Cowell's support, the singer is still trying to navigate the voice in her head that second-guesses her musical instincts.

"Not really when I'm making the song but when it's starting to get close to the day it's going to be released, I'm like, 'Oh my God, are people going to hate it?'" she explains. "I wish I had advice for myself. I don't know. I'm still trying to get through it, I guess. We're all in the same boat."

Teen Vogue caught up with Grace to talk about where she found her inspiration for Just the Beginning, as well as how she's grown in the year since her first America's Got Talent audition went viral. She also opened up about her choice to go back to the same school she was enrolled in before she appeared on AGT, and why her being awkward isn't only relatable — it's real.

Teen Vogue: First of all, what was the inspiration behind "So Much More Than This"?

Grace VanderWaal: "So Much More Than This" is about just getting tangled up in all of the drama and stuff that really does not matter, and probably won't matter in like, three months. It's about thinking that [something is] the end of the world when there's so much more you can be thinking about. There's so much more than that, I guess. And being able to try it and see what will make you happy.

The day I was going to that producing session for the song, I [was listening to] the radio. Song after song after song after song was about [relationship drama with] boys. I'm like, "This is so dumb." There's too many songs about that. I feel like there's so much more than that. I was telling the producer about it and he said, "That's a great title."

TV: That's definitely something a lot of people focus on, especially when they talk about female artists and women in general. They focus on "Who's the new boy in your life?"

GV: It's so annoying. There's so much more to be focusing on. There's so many more topics than that. Obviously that's not what the song is about but it as definitely what sparked the inspiration to write it.
