Robyn, Arcade Fire Fight To Win O Music Awards' Most Innovative Video

Nominees will be cut from 10 to five before our debate streams live at 4 p.m. ET on OMusicAwards.com and MTV.com.

We started with a terrific 10, and now we're down to a formidable five. After thousands of votes, the list of nominees for the O Music Awards' Most Innovative Music Video is about to be cut in half.

At noon ET on Monday, voting in the Most Innovative category will close, and only the top five vote-getters will survive — a list that, right now, includes Robyn's "Killing Me" clip, the Arcade Fire's "We Used to Wait," OK Go's "Back From Kathmandu," Andy Grammer's "Keep Your Head Up" and Au Revoir Simone's "Knight of Wands."

From there, the five favorites will move on to the [article id="1662511"]O Music Awards debate[/article] for the Most Innovative Music Video, a roundtable discussion hosted by MTV News' James Montgomery and featuring producer/ Global14.com creator Jermaine Dupri, legendary music-video director Wayne Isham and Mashable's Brenna Ehrlich.

The Black Eyed Peas, Ke$ha, My Chemical Romance and more will also take part in the discussion about just what makes a video truly innovative. And during the show, the artists who are nominated for the award will Skype in to make the case for why their video deserves to win the award.

During the debate, the roundtable will whittle the top five down to a final two and then will crown one video as Most Innovative. Don't worry, your votes will still get an equal say; and if you want to take part in the discussion, you can have your voice heard by using the hashtag #MTVOMA.

The O Music Awards debate will stream live on OMusicAwards.com and MTV.com at 4 p.m. ET on Monday. Of course, if your choice for Most Innovative Video isn't in the top five, well, there's still time to get it there. Voting for the award closes at noon ET.

The inaugural O Music Awards will stream live from Las Vegas at 11 p.m. ET/8 p.m. PT Thursday on OMusicAwards.com. Tune in to see who will reign supreme in categories like Most Viral Dance, Funniest Music Short and NSFW Music Video!
