what are you exactly doing with the "score"?

i hope i don't sound stupid i really dont know what to think with that
if you watch history of japan, you will notice that in addition to the singing parts, there is also music, riffs, sounds, etc. almost the entire time i am speaking. that is the score, and it is catered specifically to fit every moment of the video, for maximum impact. that is my secret for saying such dumb stuff and having it seem cool
