Good idea but your singing is atrocious.
The idea was unoriginal but funny and would have been great had you sung the song and not whispered it. It was hard do watch the whole thing but I make a point to if I'm going to review it. I'm not an excellent singer myself but I know I and most people could do better than that. I would normally review the actual animation for a flash animation but we know it's bad and the whole thing revolved around the song. Get a good singer who actually sings and does not whisper then get out of breath.
I'm gonna go listen to some good music to compensate.
