Reggaeton

Reggaeton is an urban form of music which has its roots in Latin and Caribbean music. Its sound derives from the Reggae en Español from Panama. The genre was invented, shaped and made known in Puerto Rico where it got its name; most of its current artists are also from Puerto Rico. After its mainstream exposure in 2004, it spread to North American, European, Asian and African audiences.

 Lyrics tend to be derived from hip hop rather than from dancehall. Like hip hop, reggaeton has caused some controversy, albeit less, due to alleged exploitation of women

This new genre was simply called "underground". It contained very explicit lyrics about drugs, violence, poverty, friendship, love, and sex. These common themes, which in many cases depict the troubles of an inner-city life, can still be found in reggaeton today.

But not all reggaeton is bad, some songs are love poem or other stuff, 
BUT these examples, may cause poeple to find offensive, well mabey if you understand spanish XD
