Darksynth is a sub-genre of Synthwave. And within darksynth, there’s a sub-sub-genre for cyberpunk synth music. So if synth music feels cyberpunk to you, these recommendations are a good starting point.
Here’s a higher-res version of the image (also here). This guide was created by khroshan over on reddit, I just wanted to share it.
I generally though cyberpunk was a separate sub-genre of synthwayve, not a sub-sub-genre of darksynth
I mean, they’re all just terms you use to label music to help people find more music they like (e.g. on streaming services.)
Historically, “cyberpunk” as a term emerged in the late 80s/ early 90s to refer to a variety of electronic music (source).
And “synthwave” as a term emerged after the 2000s, initially to describe electronic music inspired by 80s soundtracks (source) and “darksynth” was a development of this.
So yeah, the way this graphic classifies the music is a little odd, but in terms of laying out music to recommend, it does a good job.
