Apple Cobbler implores you to check out the music in this post, because it is presumably made of apples. That's what we told her, so that's our story and you should stick to it.
Two vocal tracks and a remix: a national anthem, some good old-fashioned 80's rock, and a AdamTh3Walker remix.
1) National Anthem of The Equestrian Democratic Republic - Full Version
2) Party In Equestria
3) Magnitude Zero fixes AdamTh3Walker - Make Some Time To Close Your Eyes
