These two dissenting understandings of hip hop's scope and influence frame debates that revolve around hip hop's possession of or lack of authenticity. Anticipating the market arguments of Tate and others, both Gilroy and Weheliye assert that hip hop has always had a different function than Western popular music as a whole, a function that exceeds the constraints of market capitalism. Weheliye notes, "Popular music, generally in the form of recordings, has and still continues to function as one of the main channels of communication between the different geographical and cultural points in the African diaspora, allowing artists to articulate and perform their diasporic citizenship to international audiences and establish conversations with other diasporic communities." For Paul Gilroy, hip hop proves an outlet of articulation and a sonic space in which African Americans can exert control and influence that they often lack in other sociopolitical and economic domains.
