Albany County has a significant Black population but the Black population of the 6 county metro on which Arbitron ratings are based is only 6.6%. The Hispanic population comprises only 2.6% of the metro. It's just a very lily white market and a lot of the songs which were hits in more ethnically diverse markets don't have the same level of popularity here.
As for Classic Country, it might eventually show up on an HD channel or as an internet radio station. Of course, Garth, Alan Jackson, Reba, & George Strait rather than George Jones, Tammy Wynette, Hank WIlliams, and Loretta Lynn would be the mainstays of "Today's Classic Country".
