GamerGod9590 shared some chords for the two season three songs—I Wasn't Prepared for This and Ballad of the Crystal Ponies. The chords are very well done and should be a great resource for guitar or piano players. Go take a look!
GamerGod9590 also shared a piano cover of The Ballad of the Crystal Ponies/Crystal Fair Song. You can listen to that in the video. It sounds great! You can find GamerGod9590 on Youtube as well.
