We're talking about Psy, of course, the K-pop savant and YouTube sensation behind the song "Gangnam Style." Poor Psy didn't make it a single one of the Recording Academy's 81 different categories. 
  
 The rest of the list is pretty much what you'd expect. Newcomer Frank Ocean scored six nominations, as did the relative old geisers Jay-Z and Kanye West. Mumford & Sons also got six. Fun. is the real standout, though, with six nominations of their own, including what The Los Angeles Times calls "a rare Grammy nomination grand slam," having secured nominations for Song of the Year, Best New Artist, Best Pop Duo/Group Performance and Best Pop Vocal Album. We've listed the nominees of the major categories at the bottom of this post. 
  
 But back to our original topic. Where is Psy's Grammy nod? In just four months, the 34-year-old pop star's "Gangnam Style" snatched the record for the most watched YouTube video in history. Just as quickly, Psy went from being a relatively unknown entity to a household name in the United States. He's been recognized as an "International Sensation" by United Nations Secretary General Ban Ki-moon who said he wanted to work with the pop star. He's won several of Korea's top civilian awards, including the Okgwan Order of Cultural merit. He's taught that funny horse-riding dance to pretty much every celebrity on the planet. (Ban Ki-moon is no exception.) If you've been following the awards circuit, though, Psy is getting more credit for the video than the song. And can you think of any other terrific Psy songs that have been stuck in your head? Neither can we. 
  
 Psy isn't the only one missing from the list of nominees. Depending on who you talk to you'll probably hear gripes about Justin Bieber not making the list. (See earlier comment about song quality.) Don't worry, though. He'll be just fine, as will Psy. Bieber still has his zany interpretation of fashion -- and lots of money -- to keep him him happy. And Psy still has his dance moves -- and lots of money.

Solution:
The Grammy Awards celebrated the diversity of music as six different artists tied for lead nominee: Kanye West, Jay-Z, Frank Ocean, Dan Auerbach of the Black Keys, Mumford & Sons, and fun. Auerbach received five nominations as a member of the Keys and also is up for producer of the year. Indie pop band fun., who performed on last night's live CBS special, rode the success of its anthemic hit "We Are Young" to a sweep of the major categories, earning nods for best new artist as well as song, record, and album of the year. R&B singer Ocean snagged the major nominations best new artist, record of the year, and album of the year. British folk-rock band Mumford & Sons is up for album of the year for Babel, one of 2012's best-selling releases. Most of 2012's inescapable hits are represented in some way—Gotye's "Somebody That I Used To Know" is up for record of the year and Carly Rae Jepsen's "Call Me Maybe" garnered a song of the year nod. Drake, Rihanna, Taylor Swift, Kelly Clarkson, Jack White, and best new artist nominee Hunter Hayes were among 16 nominees with three nods. But the Atlantic Wire noted two conspicuous names missing from the list: Psy and Justin Bieber. Click through for the full list of nominees.
