Good timing, at least.
You asked for a review. :)
Well, animation-wise, it's not the most amazing thing I've ever seen, but the timing with the song was almost perfect, which made it flow pretty smoothly.
The graphics at the beginning were decent, especially when it had all of those pictures changing with the animated character flashing in and out. Once the flash started with the pink-faced version and the boom box and the stadium lights, it got a bit less interesting, and started to feel tedious toward the end when it was nothing but the heads and wine glasses flashing and rolling around. And then, well, it ended, without anything special.
Variety would have helped here a lot; you only had a couple of very basic themes and images in here which were repeated many times, and that got quite boring by the end.
It's a great song, and a good flash anyway, and I did vote to pass it, but for your next movie, please consider adding some variety. That would do wonders for your work.
