This article concerns Dr. Remmy Ongala, a Congolese-Tanzanian musician, and the making of postcolonial cosmopolitan music in Dar es Salaam, Tanzania. It argues that Dr. Remmy's music is shaped by the postcolonial consciousness and conditions of contemporary Tanzania. It also shows Dr. Remmy's cosmopolitan citizenship in his songs that address political and social issues. Focusing on his involvement in worldbeat festivals, it argues that he, like other musicians, enters into the worldbeat system not as a fully autonomous individual but as a constituted postcolonial subject, compelled to shape his music in accordance with the demands of the worldbeat system.
