It follows the melody of "Lullaby for a Princess", and shows Luna's (or rather Nightmare Moon's) perspective on the events leading to her banishment.
- Answer Song: To "Lullaby for a Princess".
- Distant Duet: Becomes this when combined with the original. Believe it or not, this actually happened.
- Dramatic Irony: Luna sings about how Celestia doesn't care about her and coldly banished her to the moon for no reason...when the audience is aware that Celestia is grieving over having to banish her little sister and considers herself a fool for not noticing Luna's suffering until it was too late.
- Foil: Luna to the other version of herself featured in "Luna's Reply", who regrets her rash actions and wants Celestia to forgive herself for banishing her, knowing it was the right thing to do.
- It's All About Me: Ironically enough, while she accuses Celestia of being selfish, the song reveals that Luna/NMM fits this trope to a T. All she wants are "power, and glory, and praise", and she never even hints that she might love her sister (anymore).
- Never My Fault: Luna drops all the blame on Celestia, not even trying to consider that isolating herself and then doing a FaceHeel Turn might not have been the best way to win her subjects' hearts.
- Non-Appearing Title
- Recycled Lyrics: Not all, mind you, but there are some lines taken straight from the original. It's not actually a bad thing, since it helps establish the parallelism between the songs.
- Terms of Endangerment: Luna still refers to Celestia as "Tia", despite being angry at her.
- Villain Song: For Nightmare Moon as she reflects on the events that led to her banishment.
