I believe taste/preference as the differentiator is missing.
The "intense + focus" music on brain.fm puts me to sleep. My coding music is ASOT weekly series, it's usually couple of hours of house and trance music where I get immersed into coding zone and once finished i take a 10-15min break, repeat.
When I concentrate I don't hear anything that's when I know I'm in the zone. It's my preference and it's surely different from yours, hence why the differentiator is missing.
