There is no “creative part of the brain” and even if there was listening to music would have nothing to do with it.

You may be experiencing getting to different understanding of sth when you switch context. Similar to when you are stack it may be better to go for a walk than keep your head on top of a piece of paper or screen. I have had many of my breakthroughs while taking a shit in the toilet in the midst of working. Others experience similar with showers and whatever.

Afaik most ppl listen to music during certain tasks because it helps focusing. Esp when working in a busy office it really helps me to listen to certain kinds of predictable music to keep me from getting distracted. It creates a sort of entrainment that helps with attention.

Some people find music itself distracting, I myself find some kinds of music distracting, or during certain types of tasks. Then it obviously it does not fill its purpose.
