22. Jean Grae
She’s named after an X-Men character, titled her next album (“Cake or Death”) after an Eddie Izzard stand-up bit, and name-checks Rudy Huxtable on her latest mixtape, “Cookies and Comas.” She even once offered up her rapping services on Craigslist ($800 for 16 bars). In short, Jean Grae is a nerd—and is there anything sexier than a badass lady nerd? To us music journalist nerds, the answer is "no."
