Yep, your right! It is nothing like the 1990's and was never supposed to be.
The article is wrong in stating that raves were re-branded in the 2000s, it was the mid 1990's in Minnesota that they started calling them "parties" and the second one that I ever went to was in the St Paul armory (a big public dome downtown).
Jazz, rock, and rap to some extent have all been sanitized to be sold to a larger audience.
Music history is something that interests me, I find it fascinating.
