The 2013 Billboard Music Awards, which took place last night (May 19) in Las Vegas, was largely a pop-, country- and rap-leaning affair. However, rock was well represented, as Gotye, Mumford and Sons and other Diffuser-friendly artists took home top prizes.

Gotye's Kimbra-assisted 'Somebody That I Used to Know' cleaned up, earning Top Hot 100 Song, Top Radio Song, Top Rock Song and Top Streaming Song (Audio) honors. The track was one of the biggest of 2012, and these awards reflected a watershed musical moment for the Aussie rocker.

fun., who grabbed some hardware at the Grammys earlier this year, were named Top Rock Artist, while the Top Rock Album honors went to Mumford and Sons for 'Babel.'
