Needing to sleep will do you. Anyways, here's something that might help you sleep, or at least relax:
It's The Eclipse, by Paul Hardcastle. From Hardcastle X (The Eclipse).
There's Eclipse of the Sun (and it's variations, if you're interested) from Hyrule Warriors.
Damn. I should revisit Hyrule Warriors. That was neat. Obviously I dug the soundtrack, but the game itself is a pretty good time, especially the completed Deluxe Edition or whatever they called the Switch port. But maybe I'm biased because I already liked Dynasty Warriors.
