What if all you heard was "dee-doo-dee-doooo, dee-doo-deet-deet-doooo!" The sweet sounds of "The Final Countdown" by Europe. Sure, it would be funny for a few minutes, but I bet North Korea isn't happy about it.
A hacker known as "The Jester" announced that someone took over the frequency at 6400kHz and "The Final Countdown" is all that is being broadcast on the signal.
Outstanding.
If you want to have musical excellence stuck in your head all day, hit play and enjoy the magic.
