Yes, No, Not Exactly, Something Interesting Might Happen

Yes
"Mainstream" is watered down by nature, Rap-heads complain about "commertial hip hop", mainstream country is waterred down, mainstream Rock is waterred down, mainstream Latin american songs tend to be waterred down. So as soca artist try to go mainstream the music they produce will become watered down.

Now this is not a bad thing, it is just a thing. The more "hard core" a cultural item is the more it will appeal to people of that (and similar) cultures only.


No
Unless C'bean culture disappears, people will always make soca music, that is just how it is. Bajans will always wuk up stink so people will always make wuk up music, even if it is low quality.


Not Exactly
Well culture is always evolving and soca will change. The mixing of RnB, Dancehall, Rap, Rock... with soca is actually health, and should happen once it is the heart of the people/singer, Edwin mix RnB with soca all the time and look at the Coconut Tree riddim. So 'the true sound of soca disappear' or soca make not be present in soca come 2047 but it would have just evolve out and not been "taken" out.


Something Interesting Might Happen
If soca does disappear, a new music will appear to meet the cultural need of the people.
