Darius Rucker's 2013 hit, "Wagon Wheel", has just been certified by RIAA as 8 times Platinum for sales of 8 million units. The song, which was written by Bob Dylan and Old Crow Medicine Show's Ketch Secor, is now one of the Top 5 best-selling country songs of all time. Darius was surprised with a plaque February 12 at the Country Music Hall of Fame. "I don't believe you," said Darius. "I don't believe this! Wow, what a testament to the fans and their love of country music."
