Correct in my experience (I sometimes work with music, sometimes with silence). Deep insight needs silence: "You want to quiet the noise in your head to solidify that fragile germ of an idea" ->
The creativity part, the few eureka I had were when pausing long enough far from the screen, be it for a pee, a cigarette, or a bike ride. Same for my colleagues.
