Is the east coast style of hip hop dying out? Lets talk about it.

So I'm sitting up chilling with my boy from new yaawk that I aint seen in awhile. We get to talking hip hop. He started praising how we mostly keep shit west coast over here. But when he go home it sound like the south and he can't stand the shit. So we sitting up watching music video channels and I really started to see what he was talking about. I did peep how a lot of east coast cats was going with the southern style just for attention. But now that I really started looking into it, you can't eeen tell the difference anymore! They sound like they from down south and even look like it now smh. Here's just a small sample of people I didn't even know were from the east coast.

Lil uzi vert(He looks like chi city lol): Philadelphia
Fetty wap: New Jersey
Rich the kid: New york
desiigner: New york(thought this retard was future for the longest)
Young MA aka female boby shmurda: New york
shy glizzy: Washington DC
post malone: New york

The list goes on, but I just heard the east coast last hope go southern smh(Hell, even uncle murder and mano gave in recently).
This seems to be the thing to do now. If this keeps up, will we be saying bye bye to the east coast sound in the near future(no pun intended)?
