The clip comes from 'Vivir así es morir de amor,' a 1978 ballad by Spanish singer Camilo Sesto, one of the most recognizable love songs in Spanish-language pop. On Spanish-language soundboards it became a staple meme sound for announcing an 'entrada épica,' an epic entrance, usually played ironically over someone arriving in an ordinary way. Like other dramatic entrance staples such as the famous saxophone riff, it survives because the contrast between the grand music and the mundane moment never stops being funny.
