The controversy surrounding "SYSTEM" goes along with Iron's lyrics toward the end of his track, where he criticizes Big Bang's G-Dragon for his past marijuana scandal, and T.O.P. for his lack of talent. 

The controversial lyrics state, "He shaved his head, but I grew mine. What's he going to pull out from now? GD b**** cheated on his fans, but pretends like he got dumped by them. Handicapped rapper T.O.P. Just change your career to acting." 

Many netizens expressed discomfort towards Iron's hurried comeback, and with a track full of disses, at that. What are your thoughts on Iron's "SYSTEM"?
