Final answer:
Hip hop is most likely the most popular music genre at the school. It started as a cultural movement in the Bronx and spread globally, overcoming various diffusion barriers and gaining recognition as a significant art form.
Step-by-step explanation:
Hip hop is perhaps the most popular type of music at our school. Originating in the 1970s from the Bronx, New York, hip hop started as a cultural movement and rapidly became a global phenomenon.
Artists like the Last Poets and Gil Scott Heron used hip hop to speak candidly about inner-city life, while others like Chuck D of Public Enemy used it to confront issues like racism through powerful songs such as "Fight the Power."
The genre experienced hierarchical diffusion, first spreading through large cities before reaching smaller towns and rural areas. With the growth of hip hop, various barriers, including technological, cultural, and political, have influenced its diffusion worldwide.
