c)music

Definition:A film score is essentially the background music of a film (which is generally categorically separated from songs used within a film). The term soundtrack is often confused with film score, but a soundtrack also includes anything else audible in the film such as sound effects and dialogue.
The song used in the intro is Lionrock Fire Up the Shoesaw.
That was ingenious how the Columbia animation's audio merged with the movie's audio in the introduction. I find that indescribably cool. The music is fast in the beginning to show that the nightclub scene is frantic. The music shows that the characters are young and having fun dancing.
The music sets the scene.The music is beats to go with the lighting. The intro is set in a club, the characters are in a club later in the movie. In the intro you don't learn anything about the characters because none of them are shown at the beginning in the club. There are a bunch of randoms in the club, all who are wanting to buy drugs.
I believe the upbeat music symbolizes the characters having frantic lives (after the drug deal) and with the lights and sound it creates a mood that makes you feel you are in the opening scene, moving hectically.
The upbeat music is similar to other films if they are set in a club or the mood is carefree because the music is one of the main features to set the scene. This scene is tapping into the idea of young people at clubs dancing and having a good time, which may be considered a social concern if the people dancing in the club are wanting to buy drugs etc. This scene is only related to other films Doug Liman has directed because of the years/era it was made in.eg,  Swingers(1996), 'Go' is from 1999. The directors idea portrayed in the opening is young people having fun and living a carefree life and this is shown with them dancing in a nightclub.
