Reggaetn is an urban form of music that has its roots in Latin and Caribbean music. The genre was invented, shaped and made known in Puerto Rico;[9] most of its current artists are also from Puerto Rico.[10][11][12] After its mainstream exposure in 2004, it spread to North American, European, Asian and African audiences. Reggaeton blends the musical influences of Jamaican dancehall with those of Latin America, such as salsa, Puerto Rico's bomba, Latin hip hop, and electronica. Vocals include rapping and singing, typically in Spanish. Lyrics are derived from hip hop rather than dancehall. Reggaeton, like hip hop, has caused some controversy due to the alleged hypersexualization of women.[13] While it takes influences from hip hop and Jamaican dancehall, reggaeton is not simply the Hispanic or Latin American version of either of these genres; reggaeton has its specific beat and rhythm,[14] whereas Latin hip hop is simply hip hop recorded by artists of Latino descent. Another aspect that makes Reggaeton different is its lyrics. Reggaetn's lyrics serve as a reflection of Puerto Rico's urban landscape, drawing inspiration from the spatial geography and everyday life of the island. Urbanism in Puerto Rico underwent significant transformations in the early 20th century, driven by shifts in the economy and population dynamics.[15] The influx of agricultural laborers to urban centers led to the creation of social "ghettos," characterized by substandard living conditions. The mid-20th-century policy response to urban poverty involved the construction of caseros (public housing projects) and the development of barrios, which, despite efforts, persisted with slum-like conditions.[15] Notably, the genre places a significant emphasis on authenticity and genuineness in urban settings. Key spaces within reggaetn songs include the discothque (the disco), neighborhoods (barrios), and the streets. The disco, in particular, holds a multifaceted role, acting as a place for escapism, self-expression, and reflection, contrasting the challenges of barrio life.[16]
