Like someone wrote before, it's the worst genre I've ever heard, pure garbage.
It came from the spanish reggae, wich is not bad, the lyrics talk about women and sex, obviously, but also the kind of relations that this people from central America have. There is one artist that made this music popular, his name is Edgardo A. Franco but he is known as "El General", he sings in a very unique way and has been the most imitated artist in this genre. But he's not part of this reggaeton thing. Reggaeton is annoying and I consider it is music for ignorants.
Reggaeton is garbage, don't listen to it.
