You really have to try IU, she is phenomenal
Other recs:
- My boys
SHINee, if you're into R&B songs
-
Brown Eyed Girls since you like Miryo's solo stuff .. Members Narsha and Ga In's solo albums are also great
-
Sunny Hill! Their last two mini albums are awesome, they're a bit like IU and BEG
-
T-ara has really addictive electropop tracks
-
B1A4 had the strongest 2011 debut for a Kpop boyband imo, and their leader composes some of the songs too!
