A hybrid of reggae and rap, reggaeton is a music with Spanish-language lyrics and Caribbean aesthetics that has taken Latin America, the United States, and the world by storm. Superstars—including Daddy Yankee, Don Omar, and Ivy Queen—garner international attention, while aspiring performers use digital technologies to create and circulate their own tracks. Reggaeton brings together critical assessments of this wildly popular genre. Journalists, scholars, and artists delve into reggaeton’s local roots and its transnational dissemination; they parse the genre’s aesthetics, particularly in relation to those of hip-hop; and they explore the debates about race, nation, gender, and sexuality generated by the music and its associated cultural practices, from dance to fashion.
