"My aim with music is to create mood enhancers for people,” says Lenka, whose fourth indie-pop album, The Bright Side, drops on June 16th. “That gives me the most joy, when people say my music makes them feel better.” And the Australian singer-songwriter’s gift for sharing her bliss has served her well. Whether or not you realize it, her buoyant, wistful songs—most notably “The Show” (off her self-titled debut) and “Everything at Once” (from Two, her follow-up)—have been soundtracking your life for almost seven years now. She’s lent a light mood to several commercials including spots from Windows 8, Old Navy, and Coke, and charm to dramedies like "Grey’s Anatomy" and "Ugly Betty," and imbued films such as :Moneyball" with graceful poignancy. In a music culture that leans heavily on branding, Lenka has stood out for willfully being herself—occupying a spot between the upbeatness of Top 40 singles and the thoughtfulness of indie albums. “Music is a wonderfully direct way to enter people’s psyches,” she explains. “Mine is about keeping a sense of wonder about the world.”
