SimTunes is such a throwback, I had to look it up on Wikipedia just to find out what it was. (In case you're curious: "SimTunes is a children's software toy designed by Toshio Iwai and released by Maxis in 1996.") But it makes for awesome pony music!
Dogman15 created an extremely impressive version of Apples to the Core in SimTunes. I can't imagine how long this must have taken. Give it a listen, you don't want to miss out on this!
Thanks so much for sharing, Dogman15!
