This Day Aria

"This Day Aria" is a song from the second season episode "A Canterlot Wedding – Part 2" of the animated television series My Little Pony: Friendship Is Magic. In the episode, the song is performed by the characters Princess Cadance (voiced by Britt McKillip) and Queen Chrysalis (voiced by Kathleen Barr). The song is a duet that alternates between the perspectives of the real Princess Cadance (who is imprisoned) and the villainous Queen Chrysalis (who is disguised as Cadance). It has been described as one of the greatest songs of the series and a fan favorite among the brony fandom.
