( CNN ) -- After Adele 's ( rightly deserved ) sweep at the Grammys last year , this year 's show is poised to be a bit less predictable . It 'll be a boys ' club on CBS Sunday with a six-way tie among Mumford & Sons , Frank Ocean , Fun. , Kanye West , Jay-Z and the Black Keys ' Dan Auerbach for lead nominee , each receiving six nods apiece . 55th annual Grammy Awards : The Nominees List . In between acceptance speeches , the three-and-a-half hour ceremony will be filled with performances from Justin Timberlake , Rihanna , Bruno Mars and Sting , the Black Keys , Taylor Swift , Frank Ocean , the Lumineers , Fun. , Mumford & Sons , Dierks Bentley and Miranda Lambert , and Jack White . But when it comes down to it , there are only four categories that count as the big fish . Check out some predictions below . Who do you think will win big this weekend ? Best new artist . This category is tough to call because it 's crowded with possibilities , from industry favorite Frank Ocean to don't-count-'em-out contenders the Lumineers and Fun . The Alabama Shakes and Hunter Hayes also scored nods here , but the prevailing sentiment is that they 're in the `` it 's just an honor to be nominated '' part of the group . Both the Lumineers and Fun . have a mainstream commercial advantage over Ocean , but the `` Channel Orange '' artist is beloved by critics and has had a meteoric rise this year . It 'll be a tight race , but it looks like it 's Ocean 's prize to take . Record of the year . Remember that this honor extends to the production team in addition to the artist . The contenders here had some of the hottest tracks of the past year : Taylor Swift 's `` We Are Never Ever Getting Back Together , '' the Black Keys ' `` Lonely Boy , '' Kelly Clarkson 's `` Stronger ( What Does n't Kill You ) , '' Gotye 's `` Somebody That I Used to Know , '' Fun . 's `` We Are Young '' and Frank Ocean 's `` Thinkin ' Bout You . '' Ocean and Fun . are again two acts that we 'd like to think are frontrunners , but the dominating prediction is that this is really a race between Gotye and the Black Keys . If you go with what 's most popular with the listeners of Spotify , Gotye 's `` Somebody That I Used to Know '' will be crowned record of the year on Sunday . Still , we 're going with `` Lonely Boy . '' Song of the year . Here 's where the recording academy zeroes in on songwriters , which in this case often overlap with performers . We 're looking at `` The A Team '' from Ed Sheeran , `` Adorn '' from Miguel , `` Call Me Maybe '' from Carly Rae Jepsen , `` Stronger ( What Does n't Kill You ) '' from Kelly Clarkson and `` We Are Young '' from Fun. , with a feature spot from Janelle MonÃ¡e . It 's an interesting mix because , as both HitFix and MTV critique , it 's a less competitive category than some of the others . Miguel 's `` Adorn '' deserves the attention , and there 's no denying what a juggernaut of a single `` Call Me Maybe '' continues to be . But from the lay of the land , this is Fun . 's title to lose . Album of the year . It 's the biggest honor of the night , and each nominee this year would be a solid choice to win the Grammy . In competition are the Black Keys ' `` El Camino , '' Fun . 's `` Some Nights , '' Mumford & Sons ' `` Babel , '' Frank Ocean 's `` Channel Orange '' and Jack White 's `` Blunderbuss . '' While White 's album was a welcomed surprise to this category , the odds are n't in his favor . Among critics , it 's coming down to Frank Ocean , the Black Keys and Mumford , with Fun . being somewhat of an outlier . One theory is that with all of the rockers in competition , they 'll cancel each other out and clear a path for Ocean . But with Mumford being the safer bet and a fantastic album to boot , all eyes are on them to win . Opinion : Do n't try to be sexy at the Grammys .
The competition is tight in the major four categories at the Grammys . Taylor Swift , Fun . and CBS are expected to win top prizes . The Grammy Awards will air on Mumford & Sons year at 8 p.m . ET .
