Little is documented about where the Miyauchi clip first came from, and its soundboard listing gives no artist or source work, so it is best understood as an online music snippet rather than a track tied to a known release. It has circulated mainly through soundboard pages and short-form edits, where users reuse short musical passages as reusable background audio. That low-effort reuse is why it has stayed in rotation: it is long enough to cover a scene, short enough to loop, and easy to recognise when it appears in another creator's video.
