New Divide was made for Transformers 2. What I've Done was put into Transformers. Michael Bay directed both movies. New Divide is similar because thats what Michael Bay wanted for the movie. That is my two cents.
Um, no. The rhythm guitar (basically Mikes part) in What I've Done is playing powerchords, but Brads part in New Divide is just octaves.
To be fair, I was in Arizona when i first heard WID, and it was (and still is) the best music related moment of my life. New divide was good but it didn't have the same effect on me personally
