Every year, the O Music Awards reinvent the usually staid award show ceremony with a musical twist — think Chiddy Bang's record-setting freestyle session in 2011 or the Flaming Lips' epic 24-hour run of concerts last year. And 2013 is no different.

That's because when the latest O Music Awards kick off on June 19 at 7 p.m. ET at OMusicAwards.com (where they'll stream live over the span of 24 hours), they'll also launch "Live Music Day," a huge, online-only music festival that will feature more than 50 bands, of all genres, performing live for an entire 24 hours. So basically, you get the full fest experience without ever having to leave the house (or put on pants). Win.

Kat Dahlia, Atlas Genius, Hanson and Kate Nash are just some of the artists confirmed to perform during "Live Music Day," topping an initial list of acts that also includes the likes of 2AM Club, Boxer Rebellion, Chrisette Michele, Gavin DeGraw, Luke James, Langhorne Slim and X Ambassadors. More performers will be announced at a later date.

The online event will also feature performances from the O Music Awards' Make A Band Famous finalists: Chill Moody, Darling Parade, the So So Glos, Striking Matches and Syd Arthur. During the live show, fans will be able to vote for their favorite, and the winning act will get a once-in-a-lifetime shot to play VMA weekend in August!

See, we told you the 2013 show wouldn't disappoint. And there's still time to help determine who wins one of the O Music Awards' coveted cubes — nominees include Beyonce, Psy and Thirty Seconds To Mars — at the show's official site.

The O Music Awards will launch June 19 at 7 p.m. at OMusicAwards.com and run for 24 hours. Hope you don't have any plans ... This is going to be one event you don't want to miss.
