*I might put this in the wrong category, sorry*
Alright, to keep things short: there was a song about grown-up Spike singing about Rarity from the cynical perspective of someone who was exploited by her. I don’t remember much but I am sure that song exists. It was also about Spike discovering his nature of being non-binary or gender-fluid, don’t remember which one exactly. Anyone can help? I remember that it was on the YouTube and there was a drawing of Spike showing middle finger.
