Fifteen-year-old Siahna Im sang on The Voice season premiere last night, and all of the cool judges (sorry Adam Levine) were clamoring to get her on their team. Her performance should make us feel pretty good about what's going to happen when the current teens start dominating our society and making us Periscope all our secrets.

Siahna, who has described herself as an "old soul," sang "Fever" like an old pro.
