Cultural Appropriation

[Dystopia]

So I was hanging out with my cousin the other day and he shows up dressed as the worst black stereotype available. Like a total Lil' Wayne knock off. And this idiot opens his mouth and says "I'm all about that thug life." I of course look at this fool like he's lost his damn mind. We were raised in pockets of accountants and bankers, in gated communities on the shores of Lake Erie WTF does he think he knows about "thug life". But it all got me thinking, can black people appropriate black culture? For instance I love blues music but do I really have comprehension being cosseted most of my life to appreciate it in its fullness, or am I just siphoning off a cool sound?

The people who can fully appreciate the history behind the blues music are the people who experienced the history behind the blues music. 
Its not like you can't appreciate it but lets be realistic; noone from this time can really comprehend the conditions under which it was born or the motivations of its parents. Which is fine, its not a prerequisite. 
The sound can resonate in you, make you feel things deeper and stronger than you otherwise might. It could even make you relate it to certain events or conditions in your own life but thats true of everyone. It doesn't make your experience of it any less meaningful.

I think the blues example is a bit complicated to explain. Let's talk hip hop instead - Whether it is gangsta rap, mainstream, underground or just hybrid old school hip hop, it's a genre appreciated by people of different races. Now, it's fine for anyone to like hip hop - But let's imagine a few iconic songs by black rappers singing about the poverty and racism against black people... If you're white (or any other race) you can enjoy the song and even cry when you listen to it, but you simply can't understand the situation exactly like the group being oppressed in the song because you are not them and will never know in the same exact terms... Many people think rappers are dumb just because they occasionally say "nigga" during songs, but they forget that culturally it can mean a lot for a black person to say the n word to another black person (also, the majority of good artists don't say nigga that much, I can only think of Lil Wayne for that case and he is certainly not very good). 

Using an easier example to explain - I'm Portuguese, and I listen to Spanish music because I can comprehend spoken-Spanish (and read a bit) and I enjoy lots of Spanish music... I can enjoy the music, but my Spanish friends have a much deeper understanding of the artists, the meaning of each song and they relate to specific things only Spanish people (sometimes from only some geographical areas and with specific backgrounds) will properly understand. What I'm saying is not to listen to it, but don't pretend you're an expert about it. I'm not an expert on Spanish music, I just enjoy some of it. I will probably never understand the meaning of some styles of music unless I lived in Spain for quite some time.
