In Europe and so, it's not as popular as it is in the states. I'm a huge fan of it, I think it's the best style of music because it really sings people's feelings and emotions. For me, it's an emotive and beatiful type of music. It's perfect for travelling, to fall in love, to heal a broken heart.
It seems that the reason people like it so much is because it is like folk stories, it takes you on an emotional journey and the listener can learn from it. So, it's popular because it's awesome.
Because it's the best and you can actually understand what the singer is saying..unlike almost all the other music nowadays.
