Discord by Living Tombstone is probably my all-time favorite piece of pony fan music. Sometimes I listen to it just to feel pumped up.
Now, I have another great version of the song to enjoy, courtesy of Thunder Dash. He did a piano cover of Discord, which sounds awesome. Plus, there's sheet music! Thanks, Thunder Dash!
Stay tuned for what Thunder Dash is calling "a super special '20% Cooler Double Cardio Piano Remix' of Hearts Strong as Horses"—sounds super cool.
