I'm no expert, but I just have to believe after the 3 trailers, tv spots and mobile trailer, that we haven't heard one note of new music. To me it sounds like 100% BB score cut and spliced with added "percussive" hits and embelishments here and there to add to the visuals. I believe that even more now since I read the LA Times article with Zimmer saying how ticked he was that they used his BB music on another trailer even before BB came out. I have no problem waiting 'till July 18th to hear new music. Well, okay, July 1st.
Oh, and if we have been hearing new music cues in the trailers then I'm dissappointed because it sounds too much like BB. Just my two cents.
And thanks to everyone for the positive reaction to my upload. I've been a lurker for months and I thought I was overdue to give back.
