Revolutionary Girl Utena is not only a series of romantic and abstract storytelling, but also a series of great music.
Eros' Dance is a beautiful number that played during a scene in episode 3. The scene had Anthy at the ball, being set up by one of the Student Council members(Nanami). As the humiliation unfolded, Utena comes to Anthy's rescue and makes her night one to remember with a lovely dance and song(thanks to Chu Chu for providing the gem you're listening to XD)
