What's your favourite motif in The Dark Knight Trilogy?
Personally I've always loved those first 5 notes you can hear at the beginning of Molossus.
They are always played in action scenes where Batman is facing big challenges (saving Rachel, fighting the SWAT team or being chased after 8 years).
Plus, since Molossus is considered by many the most representative track of the trilogy, every time I think about Nolan's Batman those notes come to my mind.
