I'm not much good at determining what genre a song is, but I guess it's also a fairly subjective distinction, ssooo, whatever? I guess?

While it's not listed here, I also really like Synthwave. It's not listed because I only am able to find it, mostly, thanks to Youtube channels like Odysseus, who barely manage to list the artist names.
