34. Lana Del Rey
Lana Del Rey catapulted from online sensation to music world phenomenon thanks to a pair of much-talked-about performances on "Saturday Night Live" and "American Idol." Love her or (more likely) hate her, you've got to admire her ability to make people pay attention. Lana's third full-length is due in November.—Jeff Royer
