Two songs from Kumi's summer single leaked ... "lalalalala" & "TOUCH DOWN".
"lalalalala" is a generic pop-rock song (reminds me of "Hashire" ) "TOUCH DOWN" however is a nice little urban-pop number, sounds awfully familar though...
If by shading you mean "took fashion and makeup directly from CL and Minzy" then sure
they're tight. apparently too tight.
The video was shot before The Baddest Female came out. Kuu has experimented with different looks in her career for a long time. YG did not invent being hood.
