From de time you start sell your soul and change your style chasing acceptance in foreign, you lost. The foundation is the foundation.
Aside from that, the money people will always go with what has a larger, readymade audience, and even if you limit the sample to West African nations and their immediate diaspora the population numbers will always dwarf Jamaicans. It's just simple maths.
A better product will always trump numbers, so focus on the product. DJs, engineers, producers, soundman, whoever. The standards have been slipping. Take the egos out and get to work, especially with the youths coming up after(look how LONG Bounty been preaching dat). Ain't no way you could tell me Skillibeng is the best thing on offer out here. The media people will do what media people do, filter that out.
