Time to do away with "I Won't Grow Up": In 2015, the anthem of Peter Pan's Lost Boys belongs to Ruth B.

The singer/songwriter, who first broadcast her talents on Vine, catapulted to viral fame earlier this year with "Lost Boy," a beautiful, broken down musing on finding salvation that nearly nine-million YouTube viewers have seen. Now signed to Columbia, she's made her way into the Top 5 of iTunes singer/songwriter charts, and above, PopCrush is proud to premiere an acoustic set of the song that helped get her there.

"There was a time when I was alone, nowhere to go and no place to call home / My only friend was the man in the moon and even sometimes he would go away, too," she croons in the clip, with only a keyboard as accompaniment and wall-spanning warehouse windows as background.

Though delicate, the song's a powerful method of connecting to fans, Ruth told PopCrush.

"When I initially came up with the idea, it was just some fun words thrown to a catchy melody, but when I sat down to actually write it, I really did want to give it a message," she shared. "The song had a lot of potential to just be about Peter Pan, fairies and pixie dust, but I wanted people to be able to relate to it."

And it's not an aversion to growing up that Ruth sees as Pan's enduring message—it's finding the space and comfort to dream and create.

"I think in a sense we all have our own Peter Pans...for me, music is my Peter Pan," she explained. "It's what I go to when I'm feeling lost or down, and I think people can relate to this. It could be an actual person, a hobby, sport—anything that makes you feel at home."
