A short history of JoJo: She released her self-titled debut in 2004 when she was 13 and scored a Top 20 hit with the Kidz Bop-perfect anthem "Leave (Get Out)." In 2006, she released her follow-up, The High Road, which contained the Top 5 hit "Too Little Too Late." Along the way, she has suffered record-company bullshit and picked up a legion of stans. Last year, she released "a riff on Drake's "Marvin's Room," in which she said "fuck." Maturation had set in.
