The Black Keys' 'Lonely Boy' has won Best Rock Song at the 2013 Grammys. The tune kicks off the Ohio garage-rock duo's seventh full-length, 'El Camino,' which also came up big at tonight's ceremony, earning Best Rock Album honors.

In both categories, Dan Auerbach and Pat Carney bested some heavy hitters -- in this case, Jack White, Mumford and Sons, Bruce Springsteen and Muse -- to score another victory for good old-fashioned rock 'n' roll. The pair came into the 2013 Grammys nominated for five awards, and given Auerbach's win for Producer of the Year, the fellas are now three for three.

Later tonight, they'll compete for Album of the Year, Record of the Year and Best Rock Performance.
