DISCLAIMER! I HAVE BEEN ON THIS APP FOR NEARLY TEN YEARS I AM NOT NEW!
Muskyboi is currently driving the bird app into the ground. Unfortunately, the bird app is imo the best place to find and talk about hyperpop and adjacent pop and electronic music. So uh, idk if people are moving here but if you are, follow me. I reckon tumblr is the best alternative at least on the public internet. I am @electralyzer on twitter.
In the meantime, some artists I enjoy under this broad umbrella:
Dorian Electra
Charli XCX
SOPHIE
100 gecs
Rebecca Black
AG Cook
Danny L Harle
Namasenda
Shygirl
Sega Bodega
foodhouse (gupi and frax individually too)
DJ Re:Code
Jane Remover
Lil Mariko
Mood Killer
Alice Longyu Gao
That Kid
Chase Icon
Slayyyter
Alice Gas
Frost Children
SEBii
LustSickPuppy
(not an exhaustive list by any means but just to give y'all an idea. I also love Porter Robinson and he's definitely electronic but not hyperpop)
Artists on my list to get into under this umbrella
Arca
Black Dresses
underscores
Drain Gang
Alice Glass
Pop Stars that I like that have a lot of hyperpop audience overlap
