Later on one discovers that Ishkur roasts all of the genres in similar fashion and that this is part of the appeal. It is in the trashing of each style that Ishkur reveals what makes that type of music unique.
If you start to place positivity above expressiveness in art criticism, you get puff pieces that don't teach anyone anything. People love this guide not because they want to feel good about being a snob but because they actually learn about music.
For example, in the guide for New Jack Swing he makes the argument that Thriller aged better than Dangerous or Bad because of the drum sounds, I might or might not share his assessment, but the point he made about the tinniness of the drums was well-taken.
Ishkur's guides have always had this tone. It is part of the fun. Even when he is trashing your preferred genres, you are laughing. Or I am.
However, it's rather clear from the update timing that he's not getting younger, and you can't really follow all the micro-scenes these days unless it's a full-time job, so I won't be surprised if the guide's spirit is not the same.
Spent so much time browsing an older version, so happy to see it again, so sad that Casiocore apparently did not make it into the current incarnation. "Just push 'samba' on that thing and away you go."
These "genres" mostly fit very comfortably into their parent category. Even to the point that if you treat it as a strict history of the music, the majority of the subgenres are unnecessary.
It's poorly presented in this regard. It doesn't do a good job of delineating the music and the cultural history.
What is being taken as genre bashing is really tribalism and the subcultural awareness of the author. In contrast to it's failings as a strict musical history, it presents extremely well the cultural history around the music.
