Funkmaster Flex is a New York hip-hop DJ and radio personality famous for loud, dramatic on-air drops and for championing new records. Otis is the Jay-Z and Kanye West song built around a sample of Otis Redding, and its driving soul beat made it a favourite for DJ intros, car videos and highlight edits. Short soundboard clips that combine a recognisable DJ voice with a well-known beat travel easily between creators, because they work without context and instantly set a confident, celebratory mood.
