Puerto Rico is perhaps the single biggest center for production of reggaeton. The roots of reggaetón lie in the 1980s "reggae en español" of the Panamanian artist El General and certain songs by Puerto Rican rapper Vico C. In the early 1990s reggaeton coalesced as a more definitive genre, using the "Dem Bow" riddim derived from a Shabba Ranks song by that name, and further resembling Jamaican dancehall in its verses sung in simple tunes and stentorian style, and its emphasis—via lyrics, videos, and artist personas—on partying, dancing, boasting, "bling," and sexuality rather than weighty social commentary. While reggaeton may have commenced as a Spanish-language version of Jamaican dancehall, in the hands of performers like Tego Calderón, Daddy Yankee, Don Omar and others, it soon acquired its own distinctive flavor and today might be considered the most popular dance music in the Spanish Caribbean, surpassing even salsa.
