Hip hop is a type of culture/art style that started in the 1970s in the Bronx. It began in Jamaican American, African American, and stateside Puerto Rican urban areas in some of the larger cities of the United States. Hip hop uses rapping, where the rapper or group chants or says words with a rhythm that rhymes. The lyrics of hip hop songs are often about the life of urban people in the big cities. Some hip hop song lyrics are about gangs, violence, crime, strippers, partying, money, sex and illegal drugs such as marijuana, cocaine, promethazine, xanax, percocets, ecstasy and molly. Hip hop music also uses musical styles from pop music such as disco and reggae. Rap and hip hop music have become successful music genres.
