Rap music as one of the elements of hip hop culture originated in New York's South Bronx neighbourhood in the late 1970s. Its lyrics provide a powerful lens through which to view the many dimensions of the African American predicament. As a form, Rap music is for African Americans the means to pen down their history and social circumstances and forge their identities out of the white oriented and white dominated American society and culture. The dominant discourses have relegated African Americans to the margin and excluded them from the power, profits and privileges that Whites overtime have enjoyed in American society. By devaluing the blacks in every possible manner, Whites were able to hold in place the racial hierarchy of the American society. Thus, this dissertation explores rap songs as the medium through which African Americans reflect their predicaments and not only challenge dominant discourses but project their ethnic identities as well. The study deploys postcolonial theory in analysing the selected rap songs based on the relations between Whites and Blacks on American soil and how the songs are used in expressing identity related issues such as racism, marginalization, politics, legal and economic disparities. The study finds out that African American ethnic identity emerged from an identification that is rooted in perceived commonality of oppression, suppression and marginalization.
