You guys should check out LOONA! They are a predebut girl group which members are revealed one by one by dropping solo music videos each month. 11 of the 12 girls have already dropped their solos and they're all amazing! This is the most popular member yet, Kim Lip with her song Eclipse.
As I write this, I have 36 of their songs on my iTunes. The material they released in their first few months was really good, but "Eclipse" was the real game-changer for me. Everything from "Eclipse" onwards has been simply amazing.
P.S. I have a huge crush on JinSoul. Even when she's wearing that eyepatch in the "Sweet Crazy Love" music video, she still looks gorgeous.
