Cutie Mark Crusaders. I have an affinity for 80's rock, and this was pretty much spot on. Okay, the vocals needed some work, but they're fillies, so it's excusable. That and the animation/camera angles/reaction shots during the sequence is the clincher. A close second is So Many Wonders. It feels right at home in a Disney flick or a Broadway show IMO, and I've always been a Disney fan since I was a kid, so that struck a chord with me. Plus Fillyshy is so adorable!
