Still having some insomnia-related brain issues, but I feel like I need to post this.
I don’t believe there’s anything like an objectively best song or anything, but there are best songs for the moment. Sometimes they’re weird. Like this one, which requires some explanation. A long time ago there was a game for the Game Boy Advance, called Drill Dozer. It featured a walking tank with a drill on the front. You powered it up by collecting gears. Third gear was the most powerful upgrade you could get, and you knew this because it had it’s own theme song, which is embedded above. The game is long gone, not playable on modern systems, (unless you’ve got the cart) which is such a shame.
