Kernkraft 400 was released in 1999 by Zombie Nation, the project of German producer Florian Senfter. Built on a melody inspired by the 1984 Commodore 64 game Lazy Jones, the track became a major electronic hit across Europe in 2000. Sports fans adopted it soon after, and its chant-like riff became a staple goal song in football, ice hockey and American sports stadiums. That stadium life kept it familiar for decades, helping it cross into gaming videos, remixes and meme edits online.
