Michael Jackson's grunts, shouts and ad-libs became one of the most recognisable parts of his vocal style, appearing throughout his stage performances and studio recordings. Fans and editors later isolated those moments into short clips, and compilations numbered in series, such as this fourth entry, began circulating on soundboards and video platforms. Because the sounds are so distinctive even without music, they work instantly as shorthand for showmanship, effort and drama, which keeps them in regular use for reaction videos, edits and memes long after his performances first aired.
