The O Music Awards are back once again. And this time, they're taking the bus ... all day long.

Yes, on June 27, the digitally driven event will let someone else take the wheel as they play out aboard a tricked-out tour bus that will travel through the Mississippi Delta, the birthplace of rock and roll. The trek -- from Memphis to New Orleans -- will take place over 24 hours, making the O Music Awards the world's first 24-hour awards-show live stream.

Of course, that's not the only first that'll take place during the show. In keeping with tradition, the O Music Awards will also see another attempt at a Guinness World Record as the Flaming Lips ride along aboard the bus as the de facto house band and aim to break Jay-Z's record for the most live concerts in 24 hours by playing gigs in eight different cities.

"I don't remember if I was asked or if I volunteered. ... But I've accepted the job of not driving but commandeering the Magical Mystery Merry Prankster bus," Lips frontman Wayne Coyne said. "I've accepted the attempt at breaking the world record of performing eight shows in 24 hours. And I've explained to the music freaks at MTV, VH1 and CMT that I am not a host. ... But I always liked the way Jerry Lewis would get all sweaty toward the end of his yearly telethon. To play and sing Flaming Lips songs at eight in the morning, well ... I'm open to new experiences."

You can watch Coyne go for greatness on June 27 when the O Music Awards stream live at OMusicAwards.com. That's also where you can vote for your favorites -- including Nicki Minaj, One Direction, Taylor Swift and, uh, MC Hammer -- in O Music Award categories like Fan Army FTW, Must-Follow Artist on Twitter, and Too Much Ass for TV, given to the best NSFW video.

The full list of nominees can be seen over on the O Music Awards official site. Additional performers and presenters for the June 27 show will be announced in the coming weeks.
