Electronic music is difficult to talk about in general, because anything from the synths used to the BPM becomes a differentiator. Did they sample Amen? Automatically it's Drum and Bass. Does it have a 303? Sweet that means its Acid. Slowed down sample? Vaporwave. With that mindset it's easy to see how people making music these days mix and match based on what they want to create, which in turn causes reviewers to try to point out all the different genres mashed together in a single/album. Music has a discernible taxonomy, but since it's a universal language of sorts it's easy to get into confusing positions, not unlike the same word meaning something different between two different languages. So while someone might have "true" historic ties to the original Trance genre, is that a requirement for the music they make to be truly considered Trance? Or does it forever gain the lesser label of "Trance-like"? In a similar vein, if there is a particular musical technique which is somewhat "required" for a track to be in a certain genre does music that skips that technique sometimes get classified as a different genre? Something like Polka has very particular tempo/beat/bassline - how many of those variables can be changed before it's not Polka anymore? I can understand how these classifications can be handy (especially BPM sorting as someone said it really helps DJs build a set within a few BPM) but the best I can usually do is compare music to something else I know to consider how they are similar and how they differ. I don't usually hear something and immediately consider which genre that sound effect/technique places that track in, so I guess I'm more put off by the rigidity of Ishkur on the topic than anything. Music is fluid and genres are fluid too, and while there are parallels between evolution, DNA, and musical lineage, it isn't nearly as defined as genetics. When does a genre "evolve" into another distinct genre?
