Sweden makes its pop songs like it makes its women: adored worldwide. (Or so we've gleaned from ABBA, IKEA, and beer commercials.) So it's about time the U.S. embraced this Stockholm wunderkind, whose haunting album a frosty Euro-electro twist on American girl groups should be a global phenomenon. With enough doomed romance to make the Shangri-Las cry, Lykke Li captures the sadness of unrequited love with two words that need no translation: shoo-wop, shoo-wah.
Best track: ''I Follow Rivers''
