We'll always associate certain songs with this year -- records that took the radio by storm and ones that we Can't. Stop. Singing! You know, songs like Daft Punk's 'Get Lucky,' Imagine Dragons' 'Radioactive,' Lorde's 'Royals,' Bruno Mars' 'Locked Out of Heaven,' and Robin Thicke's 'Blurred Lines,' Feat. T.I. and Pharrell -- which have all been nominated for 2014's Record of the Year. So who should take home the accolade?
