Kernkraft 400 is a 1999 electronic track by German project Zombie Nation, created by Florian Senfter. Built around a riff adapted from the 1980s computer game Lazy Jones, it became a worldwide dance hit and then a permanent stadium anthem. Sports crowds adopted its chantable melody for goals and victories, especially in football and ice hockey, and the hook later spread into remixes, trailers and online edits. Its longevity comes from that instant recognition, a few notes are enough to signal a big, shared celebration.
