From my perspective, country music has been transitioning since I was a 12-year-old kid listening to Tex Ritter, Gene Autry, Patsy Cline, and a host of others. While that transition has been slow, it seemed to almost stop during the 1980s, which was just fine with me while listening to George Jones, Whalen Jennings, Marty Robbins, Dottie West, John Denver, Roy Clark and my favorite, Glenn Campbell. From that point on, it appeared that country music had taken a new twist, mimicked early rock and roll, but the singers, both male and female, all seemed to follow the same lead. To me, this was not true country music, but I could be wrong, of course.
As for the ladies not getting fair coverage by the radio stations, yep, no doubt about it, but if you look at the ratio of male to female country, they probably get a much higher percentage of coverage than the ratio would call for. As for a lot of male singers that pretty much all sound the same, yep, that's the case with today's modern country singers - they all sound the same, and every song, to me, sounds pretty much the same as well. I sincerely believe that's why I was able to work as much as I wanted in the Florida Keys, while the have guitar will travel guys, with few exceptions, were lucky to perform one night a week, and they pulled down a whopping $75 for a 4-hour performance.
