With her brightly hued wardrobe, zingy hair bows, and outgoing personality, JoJo Siwa became one of kid culture’s biggest stars almost as soon as she made her first TV appearance in 2013. Her upbeat, confident pop matches her always-on persona, with songs like the anti-bullying anthem “Boomerang” and the rock-tinged “Every Girl’s a Super Girl” proving to be excellent sing-alongs that increase kids’ and parents’ confidence quotients. Siwa’s feisty 2020 single “Nonstop,” meanwhile, channels pop-punk and synth-pop as she interlaces tales of her frenetic schedule with her never-ending resolve to fully be herself.
