A piece of recursive fanfiction inspired by an alternate ending to "Cupcakes" that I found on TVTropes and that I found so good I wanted to write about it (unfortunately, I don't know who the writer of the original piece is). So, one day, Pinkie founds an album of Tyler, the Creator in Fluttershy' place. It's "Goblin". Which launches the discovery of human music by all of Equestria. And they think it's pretty cool.
