Hip Hop is a style of African American music in which African Americans chant over beats. It originated in the 70's in the South Bronx. Originally DJ's would loop a specific cut from popular funk or disco songs known as break beats. Eventually African American MCs would talk over the beats, mostly regarding the incredible skills of the DJ. This evoloved into the MCs talking about themselves and the amount of power money and sexual prowess they possessed.
Hip Hop music is widely regarded to be one of the primary agents responsible for the corruption of America's youth the downward spiral of morals, and the erosion of Christain values in American society.
