Usually I don't actually listen to music. I found letting myself focus without anything taking my focus away actually makes me more productive. I am a heavy rap/hiphop listener so for me it was a major distraction.
I have nothing against music with no vocals though and have found plenty of happiness from Bach's Brandenburg Concertos. It's a timeless piece of art. A more contemporary artist whose music doesn't take anything away whilst coding would be The Weeknd for me.
This is quite interesting. In my relations, I have subconsciously witnessed racial bias at play without people seemingly aware. I guess a lot of associations we make are based off things we see and not consciously decide on in a forceful way that reinforces those beliefs to us as something we stand by.
Much of it is down to nature. Minorities usually don't get preferential treatment when dealing with people who just don't relate naturally with someone they don't share natural similarities with, first-off physically.
I think it's really great that we have strong movements against racism and other forms of stigma stereotypically-related but doing away with it totally remains a job of nature...and people just being naturally different. Am I painting a gloomy-picture, I hope not. I haven't come to a good conclusion on what needs to be done to shake the associations we make in our subconscious minds that affect others unfairly.
