25. Lykke Li
Sweden’s second hottest export (what’s their hottest? keep reading, all will be revealed!) is a pint-sized oddball who’s been known to play kazoos and sing through bullhorns during her live shows. She also has a knack for writing bewitchingly sexy songs like “Get Some,” on which she sings “I’m your prostitute” over jungle drums and twangy surf-rock guitars. She’s still not a household name in the States, but she should be—even if we’re still not sure how to pronounce that name correctly. Licky? Lickah? Leckah? Whatever you want to call her, she’s a firecracker.
