Two perspectives/examples to compare:

Eek-A-Mouse (Jamaican singer) venting about foreign singers (and locals from privileged class) stealing the spotlight from the sufferas:

I have to admit I have a similar feeling when someone says, "Hey, Gibb, have you heard this Hasidic Jewish guy (Matisyahu) who sings reggae? He's really good." What's so great about him that I need to hear it? So what if he does a passable version of reggae for the ears of outsiders? There are so many great Jamaican artists that one could never scrape the bottom if they only looked at Jamaica. So why would I necessarily look to this American guy just because he is being put on the TV because he is a novelty? If he were my friend, I would support him. Not being my friend, I have no reason to disrespect him. Nevertheless I would naturally look to the artists involved in and accepted by the native culture of reggae music, first -- who are masters of all the subtle aspects of the music that bring satisfaction.

Gotta respect Eek-a-Mouse for speaking his mind, advocating for the "people who grow with reggae music" and not taking the liberal "it's all good" approach.

Second example:

Not only is David Rodigan, a White man from England, very widely accepted/respected in his genre (reggae sound systems/clash), many Jamaicans consider him to be among the best. Part of this is because he has developed the relationships and gone through the experiences to earn that respect. He has not been exploitative (either actively or passively). And, luckily, in this particular genre, one's "skills" ultimately count for more than one's nationality/color/etc.
