Masta Wu path to stardom shares similarities with label-mates Jinusean because he too started off under the guidance of former Deux member Lee Hyun Do aka D.O. Prior to his involvement with YG, he was know as Ginnwon and featured heavily on other hip-hop albums such as the aforementioned D.O.'s album Hip-Hop.
Many fans tend to say that along with the transformation of alias from Ginnwon to Masta Wu, and the signing with YG, the MC has "fell off" and "sold out". While initially being respected as an underground MC, long time fans often claim that Masta Wu has watered down his lyrics and changed his style to better accompany the 'Hip-Pop' or poppish styling of YG Entertainment group. However, despite any negative critical reaction, Masta Wu now finds himself more in the spotlight than he ever was, much in part to the additional exposure signing with YG has gotten him.
