Larsson was first discovered by the Swedish public on a televised talent show when she was just 10 years old. Now, at 18, she's got a singing career and a whole team behind her (she signed to her first label when she was just 14 and already has a studio album out, called 1). So, why does it take a bit for us Americans to learn about burgeoning talent like Larsson?
"I don't know how you break out in the U.S.," Larsson admitted. "What I can see and feel is that it takes a lot more time in America. Because it's so big."
Larsson has no problem with taking that challenge head on. She's currently trekking the world promoting her music, including a new song with David Guetta, and getting us ready for her second album, but she knows that she has to be patient.
"It takes some time for a song to travel and grow," she said.
