it's iconic to the movie

Iconic? No.

Which is it? :P

But you don't associate specific songs to specific movies, because they were a part of the soundtrack?

Maybe that's because I still the song with Ally McBeal...

Also, I wonder since this was a teaser, they don't want to give away too much of the movie (obviously) and may not want to give away the score for Vol 2 (since Vol 1 was a pretty big hit).

Oh yeah, I totally agree, and referenced it was a teaser.
Maybe I just don't like teasers.
