I am not a hardcore fan of country and western music but I really enjoy this performance. Also, considering the current state of Caroline's game the sombre tone of this seems entirely appropriate.
I'm certainly not a fan of this type of music either, but I have to say it's a nice song. Even though I would do without the male voice or replace him with another singer.
By the way, I'd like to thank you for introducing me to Alison Krauss. Her voice is beautiful. I'm quite sure I've heard her name before, but that was it. Now I'll remember her.
Metal? I don't know. At best I would call it mellow metal. It has a nice riff, but the song lack of power and grunting (not that I'm a fan of grunting anyway). However, I must admit that I don't know much about Swiss metal.
