The purpose of this paper is to identify the concepts that prevail in American hip hop songs, in the period 1990-2000, when hip hop experienced its first commercial expansion in the music industry. Selected genre and songs have been analysed in the context of the political problems of the African American community and racism in the United States and the formation of a hip hop social movement. The methodology used in the paper is content analysis. The selected songs, 146, and their respective authors were chosen according to the principle of debut albums of the early performers and musicians of hip hop genres at the beginning of the 1990s. Content analysis found common features of selected songs that demonstrated the concepts that prevail in hip hop songs from the 1990s to 2000s: skin color references, references to negative stereotypes about African-Americans, references to sexist remarks to women, references to the police in a negative context, references to weapons, references to drugs, and references to criminal acts and violence. The hip hop genre and the social movement that formed around it drew the attention of the public and power institutions to various forms of racism in American society that survived the efforts of disaggregation and integration policies. Hip hop became the most visible symbol of the African American community in the 1990s, and through the musical expression continued the struggle for the rights and dignity of the African American community in the United States.
