Answer:
That they're many different genres of music, and that they all appeal to huge groups of people. I didn't know the amount of impact music has had on the world and learning all these different types of music genres that originated from different parts of the world really showed me that many cultures around the world have a certain interest in a certain music genre. For example, America has Hip-Hop and rock-n-roll, Japan has K-pop many different music genres but from many different places around the world.
Hope this helps.
