I pretty much paid K-Pop dust until early last year I got into some bops nnn
Here are my favorites~
Brave Girls "After We Ride"
EVERGLOW "Don't Speak"
EVERGLOW "LA DI DA"
EVERGLOW "UNTOUCHABLE"
Weki Meki "Cool"
Weki Meki "Dazzle Dazzle"
Weki Meki "Siesta"
+ nearly all of K/DA's songs so far
I also like AleXa "Wonderland" but I just got into that last week. There's a few big groups I've tried but they didn't stick with me, I prefer big production K-Pop that's done RIGHT.
