Hiphop isn't dead..just a bunch of pseudos in the mix with it.I won't say mainstream bc there are a bunch of underground cats that are pseudos as well.There's some raw, real, true hiphop still being made It's like looking for natural herbs it's rare but there are still people producing.You have to know where to get it.That link u posted is i will agree flat out asswater though.It's sad, but i say continue to support the rawness  worldwide or local or if you're an artist continue to stay true to your art.
