Congratulations are in order for alt rockers Metric, who are's latest Sound Off victors. The Canadian band overtook the Cribs with their new track 'Youth Without Youth,' which appears on their forthcoming LP 'Synthetica.' Today, Emily Haines, James Shaw, Josh Winstead and Joules Scott-Key will take on electro indie poppers Reptar and their new track 'Orifice Origami.'

It's been three years since Metric have released a new album, and from the sound of their first single, 'Youth Without Youth,' the four-piece outfit will not disappoint with 'Synthetica,' slated for release on June 12, 2012. The anthemic track is a blend of whirring synthesizers, heavy drums, and frontwoman Haines' ethereal and haunting vocals.

Meanwhile, the ultra fun "disco dust" guys known as Reptar get us up off our thangs and dancing till we feel a whole lot better with 'Orifice Origami,' which appears on the Athens, Ga. natives' album 'Body Faucet.' With a sound that's slightly reminiscent of other electro indie pop bands like MGMT and the Naked and Famous, but with edgier rock vocals, Reptar bring the funk with 'Orifice Origami,' a dreamy, hand-clapping tune that is nearly impossible not to groove along with.

Metric's 'Youth Without Youth' and Reptar's 'Orifice Origami' may have very different compositions and feels, but take a listen to both tracks and let us know which you prefer by voting below. The poll will remain open until Wednesday, May 9 at 11AM ET.
