I agree with you on hip-hop. It's very important to me. And it's great that it's become so ubiquitous. But it wasn't always like that. Early hip-hop was just music created extemporaneously at a party or a park jam. It wasn't even recorded. It didn't fit the format of "about 4 minutes and some seconds." And the whole mixtape era was music of the moment, not even an official release, mostly a promotional product.
