This is just too awesome not to share. A brony has made a 3-minute music video with original animation, original voice acting, and original music.
Words cannot express how impressed I am. The first time I saw it I was going "Wait, I've seen the episode with Photo Finish in it, I don't remember any of this," and then it proceeded to annihilate all my expectations.
It looks like it came out of the MLP studios, it's that well made.
