1. I'm "Irene" years old and set in my ways. Breakthroughs either happen or they don't.
2. 2nd Gen and 3rd Gen still keep me well-fed, with 4th Gen sometimes entering heavy rotation.
That's pretty much it. #1 is especially important, because I don't typically seek out new groups. If Google Music throws a new song in my rotation, I might get into it, I might not. There are several GGs and female soloists that have been thrown into the radio mix that I've been like, Oh, I like that... but I'm still so focused on keeping up with 2, 3, and some of 4 that I put my "new artist discography deep dive" onto the backburner.
Also, I shouldn't have answered because I'm not a "stan," so I don't get too heavily involved in K-Pop spaces in the first place.
