You'll notice how Taylor Swift is missing from the above playlist of country artists. Anyone who has to remix their music to gain more airplay outside of the country genre should not be considered a country artist. Plus she can't sing. And she looks like a wet rat.
The only thing I can say is that everyone should give country music a listen. I will agree that country music is not everyone's cup of tea, but for me, it's the epitome of great music.
And also, I'm pretty sure there's a high correlation between growing up in small towns and liking country music.
