The cover of this 2010 song from Katy Perry is lacking in some very important areas, and by far the greatest is the complete lack of any kind of Firework. How can you have a song called Firework and then not have sight nor sound of a Firework on the cover itself. That needed to be fixed, and fixed is has been. On the remix we see a girl (not Ms Perry in this case) who is being turned into a Firework. Ouch!
