This is why I no longer listen to 'country' music, but instead listen to bluegrass. While there will always be similarities in music (after all there is only so much you can do with a limited number of notes - this is math after all) there is something that is just too much of an 'algorithm' to a lot of music today. There was some discussion a while ago about how the money behind the music now use software to analyze music to see if it has the 'components' to be a hit song. No wonder everything sounds the same.
Another reason to like the old days, where each town had its own DJ, who selected the songs that were played for that station, and a small band could come in to the station and might just get a break and have their record played. Lots of good and different stuff was found that way.
