I'm the same, for the most part. I worked at a small dev shop with two coworkers. One liked to put on classical music, and the other would often play whatever the hell kind of music Pat Metheny is, and while the richness of those particular genres appeared to _stimulate_ their ability to code heads-down, it rendered me pretty much useless. My attention would glom onto the scales and arpeggios of Vivaldi's Four Seasons or onto the weird proggy time signatures of the other stuff.

However, I have had much success with black metal bands that shriek (or whatever) in a foreign language. The fullness of the sound - blast beats, distorted guitars - just really does it for me for some reason. And I don't get distracted by the vocals because I don't understand e.g. Finnish (and with bands like Horna, it's probably better that way). It makes finding that flow state much easier, and I suspect it may be working as a fidget spinner does: a certain base level of constant but predictable sensory input soothes whatever it is in my brain that gets me antsy when engaging in an activity that requires a lot of energy expenditure without proportional immediate feedback. But as soon as you up the complexity of the music past a certain point, it swings all the way the other way and makes willful concentration pretty much impossible.

Yep. It's ADHD and its weirdness with the rewards system, for sure.
