Well, I guess I should reveal how I became a Brony. I blame these guys.
I'm planning to write stories soon, so I need to know one thing first: Why do the characters go into spontaneous song? What are the in-universe reasons that you guys here have made to explain it. Please comment a detailed explanation. Thanks!
