Michael Jackson's hee-hee became one of the most imitated vocal tics in pop music, a sharp, high-pitched ad-lib he used to punctuate choruses, dance breaks and live performances throughout his solo career. Fans began isolating his vocals from studio tracks and concert recordings and sharing them as short clips, where the sound took on a second life in memes, reaction videos and dance edits. Its instant recognisability keeps it useful decades later, because listeners identify the artist within a fraction of a second, even with no melody attached.
