If you look on “cyberpunk” play-list on youtube, it’s mostly some synthwave electronic music.
if I think about Cyberpunk, I obviously think about 2020’s rockerboys with a guitar-axe, or skater like snow crash’s YT. Also, as it’s name stands it’s a deeply punk anti-capitalist. I feel like RATM or noFX would be way more suited in that genre than some DJ playing with synth.
So how did we switched from guitar to synth, and from anti-capitalism to neon aesthetic ?
Electronic music, electronic world. I don’t think it’s really deeper than that, TBH. It sounds cool and, when the cyberpunk genre was conceived, techno and synthwave were also pretty new and gaining popularity with the tech crowd IRL. It seems natural that the techno focused punks in a cyberpunk world would gravitate toward techno and synth music, though I would also imagine an evolution of styles mixing techno, punk, grunge and metal into something new, unique to a world where these genres have mingled and co-existed for a long time as part of the mainstream/counter-culture that you are immersed into while reading/watching/playing something cyberpunk.
