honestly, I don't know any of the "top 10" Winston's similar artists (beside Selah Sue) but I see that most of them are french artists so I don't know if it's a pitty or not. I am not the one who contributed them too :> But I think that it would be hard to create a good list of similar artists. not only here, but to every other artist.
Discovered this guy only 2 weeks ago. Love both his albums, ordered them today. Fantastic singer, lots creativity, great songs. I want him to become more famous in my home country (the Netherlands) too.
