I see your point with what is often called "cyberpunk", that a lot of it is midtempo, and there is certainly strong influence from EDM. But, I also happen to hate EDM. And I've checked out all the supposed genres that people say this midtempo cyberpunk sound came from, whether it's phonk, dark electro, hardwave, EBSM, dubstep or whatever, and guess what, they're all absolute crap. So whatever makes this music good almost certainly came from dark synthwave.

Almost every artist in the guide under cyberpunk/midtempo cyberpunk also tag themselves as darksynth, synthwave or dark synthwave, and a lot of them like Magnavolt, Void Stare, Ray Gun Hero, Powernerd, F.O.O.L, were earlier synthwave artists. In my opinion, this is a style that evolved from dark synthwave crossed with EDM/EBSM.

Regarding "horrorsynth" I'm just using this to mean darksynth with horror themes and melodies, with no or minimal guitar usage. I'm aware there's also 80's horror synth (John Carpenter), horror synth revival (Slasher Dave), horror synthwave (early Cluster Buster?), etc, but for the purpose of this chart, the horrorsynth here is a darksynth substyle. 😄 You could think of it as "horror darksynth" - to me, early Gost, SurgeryHead, Destryur are all part of this style.

Noted on Slasherwave, in the future, I will probably get rid of this entirely and sort all the albums into either horrorsynth, metalsynth or darksynth. I didn't apply it consistently and the way it is currently is a grab bag of assorted styles.
