It can be as it is usually about rapping but it is about the entire subculture as well.
It seems like my generation is more into hip hop music also known as rap.
I love the music from the eighties, do you? I'm neutral on 80s music but know about an article that has an overview of 1980's popular music's major trends and events. Does it mention the release of the disco during the 1980s? I'm not sure but actually the disco originated during the early 1970s. Hm.. maybe it got popular later. Well what about hip hop, is it just rappping?
While often used to refer solely to rapping, ''hip hop'' more properly denotes the practice of the entire subculture.
