The melody comes from The Legend of Zelda, Nintendo's long-running adventure series, where the Hyrule overworld theme has accompanied Link's journeys since the first game in 1986. Composed by Koji Kondo, the tune became one of gaming's most recognisable themes and has since inspired countless fan arrangements. Heavy metal versions rework its bright, adventurous melody with distorted guitars and driving drums, a style popularised by fan musicians online. They remain popular because they keep the nostalgia intact while adding the intensity gamers want for edits and streams.
