We like music because it makes us feel good. ... Using magnetic resonance imaging they showed that people listening to pleasurable music had activated brain regions called the limbic and paralimbic areas, which are connected to euphoric reward responses, like those we experience from sex, good food and addictive drugs.
For years I've been developing and pretending I can write! All jokes aside, over those years I've learned a lot about myself and my creative process. I've discovered music really does help in my productivity - turns out always having headphones in my ears on my daily commute wasn't just me being anti-social!
My preference tends to change depending on what it is I'm listening to - when I'm stuck in CLI oriented tasks I usually prefer chillstep.info. I've found the relaxing nature of the music typically tends to defuse the situation for me. The background hum tends to provide some sort of slight distraction from the drudgery of monotony.
The minor distraction that the white-noise-like background audio provides, especially when deeply involved/invested in a particular task is unparalleled. I've discovered it genuinely does allow me to hone my skills while not becoming overly involved to the point that I feel stuck should something go awry.
I linked to chillstep.info earlier on in this article, however, the video I chose to link is something completely different from what you will find there... Why is that? Because I don't relegate myself to one particular genre - I prefer to listen to as much variety as I possibly can as I've noticed the variety tends to increase my creativity - almost as if I feed off the different tonal signatures coming from different sounds.
For myself, Bongripper is a perfect example of what I enjoy when I'm in my "Creative-Mode". Notice something peculiar about the "Hippie Killer" record? Or hell, with Bongripper in general? They are entirely instrumental! It's an outright sludge-fest with no distraction of singing along!
This is simply why I enjoy music during my creative process, although, everyone is different so your results may vary!
Have you ever tried to do something incredibly involved without some kind of background noise? It doesn't have to be music, it could be the hum of a fan!
