Some of the videos in this thread contain something that should be called 'autotuned barking', but not music. What raggaeton has to do with music?
Anyway.... Piano/singing guy from Carlos's post #1,094 is good. Reminded me some Sin Bandera's tunes.
There was a good Dominican band with a Colombian singer in Santo Domingo called Auro & Clemt, I saw them live once more than 10 years ago in some crappy club in Zona Colonial, and they were really good. They got some airplay on local radio stations but disappeared in a few years. The singer is still here in DR as far as I know, doing some solo work, but I don't like it.
This is their music video from 2008:
