Ah! I see you've admitted to breaking the rule that all of us do, but won't admit to: Not listening to K-Pop everyday. 🤣 😅 .. I myself can go 2 months without listening to K-Pop, but I digress.
For January there were: (1) Taeyeon (2) Kim Jae Joong-- (3) Baekhyun/Chen/Chanyeol comebacks (4) Dreamnote (5) SF9 (6) Ateez
There were others. Of Course. But these were the ones that I liked the most. Also, there was a new group that debuted. I'll post the video:
*Baekhyun, Chen, and Chanyeol each had a comeback, it wasn't some three-way collab. I didn't want to individually list them though as that would be gratuitous.
