Is it true that there just aren't any major new genres and subcultures with music? I know people will respond with "I love new genre X" which will turn out to be a handful of bedroom djs on soundcloud. There needs to be some notability standard for a genre which IMHO is that there are multiple clubs that specialise in it and larger clubs have a regular night for it showing some general appeal. Anything else is just some micro-niche that should be categorised under an existing genre.
