A microgenre is like a special type of music that only certain people really like. Think of it like different types of food that some people love but others don't really like as much. Microgenres have their own special sound and style, and often have a small group of fans who really enjoy listening to them. It's kind of like having your own secret club where you all like the same thing. Some examples of microgenres are vaporwave, witch house, and seapunk.
