Ah, the country of great cheese, tulips and awesome public transportation. Well, awesome compared to what I'm used to at least. π
There is no actual specific genre. The Suripop contest allows any genre. Usually they are combined with influences from Suriname instruments and culture. The classic hits stay popular, but nowadays a lot of artists want to become some type of "rapper", with about 75% resulting in low quality music, in my opinion.
The contest produces some big stars every now and then though. One you might be familiar with is Bryan Bijlhout.
