You know what? This is the scariest video game music out there. Well, this video is a remix of it, but you know what? There isn't anything scarier than this ungodly countdown to death, especially in Chemical Plant Zone. Fuck Chemical Plant Zone.

Ahhh yes. 10 seconds of agony and doom as you struggle and panic, thashing about the water to find your way yo safe land.
FUCK. THAT.

Even better is when you're halfway through the countdown and you finally find an air bubble spot, but you just missed an air bubble and you die waiting for the next one...and then, as your corpse falls off screen, a bubble shows up.
Also Tails can be a dick by taking your air bubble before you get the chance. Happened to me once, I hated Tails for the rest of the day.
