SM promoting their subsidiary artist under their main channel

oh damn it looks interestingg

As far as I've seen it's just Sohlhee and Giant Pink that they've posted on the SMTOWN channel. Both are under the AIKM sublabel. Woolim and Million Market, for instance, use their own channels for their artists.

edit: I forgot they also post the Scream Records artists like Raiden, Imlay, and Hyoyeon's solo work there too... and obviously Label SJ and Label V as well, but both of those are more managerial divisions to me.
