'Record of the Year,' after 'Album of the Year,' is one of the most talked about categories every year and this year is no exception. All the nominees' songs have dominated mainstream radio last year, and it seems like any of them can win. But who will take home the award?

Will the Grammy go to Sam Smith, who is nominated for five other awards Sunday evening, or will Taylor Swift snag it away from the British troubadour? Both of them have had insanely successful years: Smith went from scrubbing toilets in bars to selling out arenas and Swift was the only artist to sell over a million records last year. Or will it go to Sia, who beautifully incorporates beautifully emotional lyricism and pop music?
