Good tunes.
The song is excellent. It is one of the most creative ideas I've heard in a while. I really enjoyed it.
But, you didn't make the music, you made the animation. And unfortunatly, the animation was a bit mediocre, and the main focus of the flash was the music.
I'm not saying that it's bad or you're a bad person for making this, I just think that if you're going to make a flash tribute to a song, the flash animation itself should be something special on its own.
