Swedish singer-songwriter Lykke Li is a busy lady this week. She has already played headlining gigs at New York's Central Park and the Greek Theatre in Los Angeles, and she'll cap off the week with a performance at Lollapalooza in Chicago. Tonight, though, she will make an appearance on the Tonight Show with Jay Leno, where she'll play a dark yet poppy number from her latest record Wounded Rhymes.
