Metal Gear Solid V: The Phantom Pain - Quiets Theme?

...
We'll plan a party with Pinkie Pie
Then watch her balloons lift her up to the sky
Scootaloo will show us games to play
Toola-Roola will be painting away
Rainbow Dash always dresses in style
Sweetie Belle's magic brings a great big smile
I hope we hear a story from Cheerilee
And a beautiful Starsong melody
