Metro Boomin is an American hip-hop producer whose spoken producer tags have become instantly recognisable markers at the start of his tracks. Clips of his tags began circulating as short meme sounds because they carry the same anticipation as a beat drop, and editors soon reused them to punctuate reveals, jokes and highlights in short-form video. Like the vine boom, the appeal is in the timing: a familiar voice promises something big, then the bass delivers it. That simple setup has kept the tag useful long after its first appearances in songs.
