Between the thumped-up beats and twang-hop of Florida Georgia Line's debut LP, Here's to the Good Times, there's nary a salty tear nor mournful ballad drowned in a pint of whiskey. And maybe that's because this duo's really never had anything to cry about: After graduating from Nashville's Belmont University, they went from unknown students to chart toppers in less than two years, in a, um, cruise to the top. Brian Kelley and Tyler Hubbard, from Florida and Georgia, respectively, wrote songs between classes, crafting an EP that landed them a contract with Republic Nashville. Their first single, "Cruise," played to a broad spectrum with its nearly genreless compilation of sounds, swung along into a party anthem by the links of their wallet chains – it went on to be the best-selling country digital song of all time. "I don't think we were ever driven by success or wanting to be a star," Hubbard tells Rolling Stone. "You do something you love, you want to be good at it."
