This specific video has helped me buckle down and get shit done so many times. I've even made loops of songs I have copies of on my computer for this kind of thing. The repetition OH MY GOD it tickles my brain in just the right way so as to boost productivity. It's great how that can cancel out the ADHD when I have deadlines looming.
Video game music does the same thing. Death by Glamour gets me in the ZONE.
The Dash Berlin ASOT 600 set (specifically Sofia) got me through my dissertation writing. Even now, if I sit down with a coffee and turn on the set, within the couple minutes I am completely in the zone for working. It’s like a brain hack for me.
I also like the Music for programming site (specifically RITES) which is also good for some focus music.
I’ve tried to get some folks to post their dissertation writing music and form a massive playlist, as it seems really common to have some certain song or album. I’m sure it’s similar for other intense work flows too.
