KPop fandom in general did too much with these debuts. No Playboy is only bland, Wa$$up isn't even bad.
For 9MUSES I guess it that:
The CEO himself stated how the problem was a mixture of the wrong song and choreography, and the girls' lack of practice and confidence.
But I watch their debut stage, and they actually served 100% live vocals
If Wa$$up happened, then "Wa$$up" would've become just as revered as something like "Hot Issue" is. And for a specific portion of the Korean population at the end of 2013, that probably was the case.
YASSSSS Blady is coming for wigs, Oochie walla Walla is the U&D of 2015
That song has already been made obsolete by this upgraded version from BADKIZ called "Oochie Chewy Wiggle Wallas":
e-ri-ro. #455 on Melon yesterday!
(Blady actually got some run when Soul.G mania brought her old group 2NB back into the discussion, leading people to wonder what happened to the other girl -- and she just happens to be Blady's main vocal. So, might as well keep hitting the EXID coattails.)
