These two sisters are trailblazers. Long before Kacey Musgraves earned a Grammy for her song 'Merry Go 'Round,' these girls cut their own version of the song. We think Branndie is the older sister, but this performance is a true duet. 

The girl on the right has also cut a version of Taylor Swift's 'We Are Never Getting Back Together' for YouTube, but it's this song that garners attention this week. Watch as they match the original singer's mood and vocal performance. It's adorably heartbreaking and a reminder of how wonderful Musgraves' 'Same Trailer, Different Park' album really is.
