Korean girls Girls' Generation and Eminem bagged the top prize at a rather new but weird debut YouTube Music Awards on Sunday.

The award show was held at an unusual venue, Pier 36 in New York, which is a dark performance space. YouTube Music Awards was organised by famous film and music video director Spike Jonze who promised to deliver something unique and different from the usual formal award shows.

Comedian Reggie Watts and "Moonrise Kingdom's" Jason Schwartzman hosted the award show and worked without a script. They were, clearly, unprepared for the show. There were awkward-silent moments and viewers wondered what was going on.

"I've never hosted anything in my life, one Christmas party and it was terrible," Jason started the show with this line and he, clearly, lived up to the statement.

Jonze was spontaneous at the award show as he grabbed the microphone from Jason and protested Taylor Swift's victory in the YouTube Phenomenon category. "The YouTube phenomenon of the year was the Harlem Shake, everyone knows that," Butler said.

To announce the Response of the Year award, the hosts had to destroy five cakes in order to find the winner. Watts cried that it felt like Nickelodeon while Jason pulled out the envelope from the cake crumbs.

Viewers took matters to Twitter and compared the show to a parody. Moreover, they called it, "a mess", "weird," "unprofessional," and "embarrassing."

Lady Gaga performed "Dope" from her new album, "Artpop." She wore a flanno shirt with a baseball cap. Apparently, she wore no pants on the day. Tyler, M.I.A. and Avicii also performed at YouTube Music Awards 2013.

Eminem won the Artist of the Year award after beating industry giants like Rihanna, One Direction, Taylor Swift, Justin Bieber, Katy Perry, PSY, Nicki Minaj and Macklemore & Ryan Lewis.

But the real surprise was Girls Generation's win in the Video of the Year category. Their video "I Got a Boy" went past Justin Bieber (feat. Nicki Minaj) - "Beauty and a Beat," One Direction - "Best Song Ever," PSY - "Gentleman," Miley Cyrus - "We Can't Stop," and Lady Gaga - "Applause."

In the Breakthrough Artist category, Macklemore & Ryan Lewis defeated Naughty Boy, Kendrick Lamar, Passenger and Rudimental. Lindsey Stirling and Pentatonix - "Radioactive" got the Response of the Year award at YouTube Music Awards.
