AHAHAHAHA
How did you know that's my FAVORITE SONG!!! OMG I saw the title and immediatley watched it.. and it was really good!
I like the idea for the style, and I applaud you for keeping it short (the full 3-and-a-half minute song in this style would of gotten boring but keeping it around 30 seconds was a good choice). One idea, though, would of been to do the part where it sounds like they're all singing at once.. I would of liked to see a fun Flash like this to that part of the song.
Good idea, and greatly executed. I am favoriting this
