Genres have become so convoluted over the years that people are now exhausted with trying to follow them and figure them out. But they weren't always that way. If you look at history, genres are not made-up boundaries that people impose on you. They come from real life people, real life experiences, and they make a movement. They come from a group of people that are mostly influenced by what they are doing in a certain place and time.

In a time before internet, radio, tv, and even the phonograph people were mostly influenced by their own surroundings, after the phonograph more influences start seeping in, and even more with the radio. Now everyone has access to anything and as a result we are influenced by everything. So in that sense you can say that there are no longer genres.

But saying that genres don't mean anything is pretty disrespectful to the people created a new sound and a cultural movement. People who's entire lives revolved around the culture of a musical experience. That's some pretty real shit.
