I used to hear to Hucci alot back in the day because most of his songs would hover around 60-70 BPM, I'd gather it was having a similar effect.

I use Erik Satie a lot (https://www.youtube.com/watch?v=5pyhBJzuixM). Also ASMR videos of mechanical keyboards (https://www.youtube.com/watch?v=_zq5blZL1P4). Wonder what a light with some randomness would do.

You could hook up some physiological monitors and try all kinds of light patterns.
