I revised the original song for two reasons - I had to do it, and I wanted it to sound better. I needed to make a one minute and thirty second song for a game our group was making in a game making class I'm taking, and it just so happened that the original theme fit the mood we were going for (the game involves monkeys and jungle running). So, I just basically changed it around, added a few things, and shortened it to accommodate our time limit. Hope you like it!
