4K 10 hours - Black Screen, Audio of Thunderstorm, Heavy Rain outside & Crackling Fireplace inside

10 hours of Pure Black Screen with Heavy Rain and Thunderstorm audio outside combined with a Warm, Crackling Fire inside. Very High quality recording. And it's in 4K! (some find it useful for a screensaver, insomnia, focus, relaxation, calming meditation or a way to prevent a computer from going to sleep, check the screen for backlight bleeding, broken pixels on the monitor etc.)
