Dimondium is a member of the Everypony Sings team with a lot of musical talents. One of his talents is transposing music, making familiar songs sound very different by putting it in a different key.
This time, Dimondium took Raise This Barn and transposed it into D (Harmonic) Minor. The cheerful hoedown sounds way creepier in this key. It's downright malevolent. Give it a listen!
Thanks for sharing, Dimondium!
