I like the country twang they have added to Season 4 rendition of the skye boat song. It speaks of the Blue Ridge Mountains. I loved the music in the movie Cold Mountain with Nichole Kidman and Jack White played in the movie. They did a concert and included all the music (always telling a story) that has been passed down for generations. They, like the Scottish are a superstitious bunch and tell stories through their music. It's so soulful and I picked up on the change during the opening of the first episode America The Beautiful. Research Jack White and let me know what you think. They have tweaked the Skye Boat Song each season and I think it is just another added genius segment of Outlander.
