Twisting by Kevin MacLeod
Let's talk about why so much film music sounds like this. The construction allows any part to be muted and otherwise sculpted around the dialog without the loss of a theme or motive energy. There isn't really a theme to lose. You can't hum this one easily. There is a lot of variation, but it is all in a very well defined range, and doesn't get too crazy.
I see this used in a 'getting ready' montage, during a solo introspective drive at night on the city streets, or a as an underbed during a thought provoking search of a victims apartment.. SO VERSATILE! Thank you!
