Celestia's Ballad was a beautiful part of the season finale. It was cool to finally get to see a little more of Princess Celestia's perspective and motivations.
I also loved getting to hear EnergyBrony's great cover of the Ballad. You should definitely give it a listen—it sounds great! Even though EnergyBrony is from Russia, his English is really good.
Thanks for sharing your musical talents with us, EnergyBrony!
