4 Hours of Deep Engine Vibration, Slowing to Dock. Headphones Required.

You'll need headphones. A phone speaker can't play bass this low. You're in a bunk on a ship with the engines running under you for just over four hours. Near the end the ship slows and docks. Nobody speaks on it and there's no music. It's on Kwalia Bliss, next to Shut Up, Brain, Shut Up, Neighbours, Shut Up, Darling and Shut Up, Everyone.
