i mean dreamcatcher, obviously, though it's not quite there due to the layered synths that necronomidol has. But i don't like those synths because it makes it sound too idol-ish in a way that i don't like, often japanese idol music that tries to be heavier seems to mix synths in a way that i don't like so i stick to strictly rock. And i find those synths take away heaviness when done in that way, so i do like dreamcatcher's approach more, though i don't like either too much
(dreamcatcher's approach feels too normal to me by now, especially after many of their songs turned out so similar. Nowadays they're experimenting more with edm, but except for Scream i haven't liked it. I do like dreamcatcher's integration of edm more than this when they actually have done it right, but neither do it well enough for me too often)
I still like non-idol rock and bands overall more whether it is in Japan or Korea, and i also like their integration of edm more than most idol groups on a general level, with some songs being exceptions like Scream (which layers the psytrance bass synth with the guitars) and a few japanese songs here and there. But overall there aren't many artists in the world who flawlessly mix electronic elements with rock (ignoring soundtrack composers), it's hard so i'm not too harsh on the topic lol.
