Lets try something new! It's time to get those creativity hats out, and plug in the lightbulb attachments.
You have been hired to write the lyrics for a pony Villian song! You are free to do it any way you please, but for most of us, the best way will probably be a parody. Find some evil-ish music on Youtube, pick a villain (Discord, Trixie, Flim/Flaim, ect) from the show, and make a parody! Toss your new custom lyrics in the comments below with a link to the video you chose on Youtube.
Alternatively, write your own!
Who knows, maybe one of the musicians in the community will see it and bust out an actual song.
