Why is the Scandinavian supertrio at Number Two on this list? Because they're bigger than Ikea and Abba combined! And now that Steve Angello, Axwell and Sebastian Ingrosso announced they're retiring from touring together next year, things have gotten ridiculous – including a Grateful Dead-like four-night arena run in New York next March. Since forming in 2008, the Swedes have conquered the planet with their super-high-gloss brand of progressive house – combining widescreen, heartbreakingly earnest pop hooks with devastating four-on-the-floor beats that stomp everything in their path, Godzilla-style. "We're just enjoying it at the moment," says Ingrosso. "People go, like, 'Your job must be exhausting.' I saw Deadliest Catch on Discovery Channel. My job is fucking nothing."
