What is the most counterintuitive piece of music that you actively use?

Normally, I fall asleep to this white noise, but for some reason, I also fall asleep to From Afar by Ensiferum and I mean that I sleep like a baby. I don't mean that I just barely can fall asleep to it. It feels amazingly good. My theory is that it makes me drift off to places in my mind that feel good, that are not of this shitty world, which in turn induces sweet dreams. No idea.

How about you? Anybody here falling asleep, studying or meditate to Dimmu Borgir's Indoctrination or the likes? 🤣😛
