The locals like Zouk, Merengue, Dancehall and HipHop
A lot of Techno and Vocal House on the French side. The major clubs fly in top international DJ's for one-off shows. Beach bars etc have resident DJ's, most of whom have lived here for years.
Don't think it's going to fly unless you already know a proprietor who is willing to offer you a residency, or unless you first become very active in the social/bar scene for at least a few months and get to know owners, bartenders - and mostly get a feel for what is being played.
You would also be working illegally and subject to deportation if caught.
