Is it cultural appropriation to make certain music genres?

Is it cultural appropriation to make certain music genres?
I am a rock music listener, I listen to most rock music genres and I have noticed that there aren't many black people in the rock industry, let alone many well known black rock stars...

Also most people are quiet territorial with music even, like I have heard people say stuff like ohhh if your not black and you are making reggae/rap/RnB music that's cultural appropriation or like black people who make rock are trying to be white and they are committing cultural appropriation etc.

what are your honest thoughts on this dilemma?
