John Williams

As it would appear, Indiana Jones has the best theme, and is the best John Williams theme (out of Star Wars, Cantina Theme, Indiana Jones, Jaws, Jurassic Park, and E.T.). Woohoo! I personally would not have been able to make that call, although I would probably say a tie between Star Wars, and Jurassic Park, but they're all some of the greatest movie themes ever, in my humble opinion.
