The star of this year's Grammy Awards wasn't a rapper or teen heartthrob. Instead, it was country-pop crossover act Lady Antebellum. The band took home five trophies that night, including Record of the Year and Song of the Year for their smash hit, "Need You Now." The song has been certified triple platinum, and it's probably been stuck in your head since its album of the same name was released in January 2010.
