Fluttershy Pony Girl (Acapella)

I used an inversion of Billy Rex's instrumental track to cancel itself from Pinkie Rose's "Pony Girl (Fluttershy Version)". This is about as close as I could get to pure acapella without clipping a bit of Pinkie Rose's voice. Perhaps a better duplication of the sound bits with a more accurate sample rate from the instrumental in the video would reduce more.
