E-Sens obviously has a major bone to pick with his former label Amoeba Culture and one of its founders, Dynamic Duo's Gaeko.

On Friday morning, the former Supreme Team rapper released a free song online called "You Can't Control Me," and 'aggressive' doesn't even begin to describe it.

The strong lyrics reveal E-Sens's anger toward the company and single out Gaeko with lines like "After you listen to this, answer me Gaeko" and "Don't try to slip out of this like the way you acted toward me inside the company for the past five years."

And that is just the tip of the iceberg.

Plenty more lines are aimed directly at the Dynamic Duo star, such as "Get real, the most devious and sly person is you" and "Cosplaying as a nice person, f*ck that."

As for his opinion about the company as a whole, E-Sens is not shy about airing his grievances.  

Lines like "Scamming people while they act like they're putting their all into supporting their hoobaes of Korean hip-hop" and "Amoeba Culture, kiss my ass" are just a sampling of what sort of anger E-Sens is expressing in "You Can't Control Me."

The song does raise a lot of questions about how the relationship between the rapper and his former agency ended.

It was announced last month that E-Sens was leaving Amoeba Culture and that Supreme Team would disband, leaving Simon D behind and still signed under the label.

Amoeba Culture announced the news by saying, "We have told E-Sens that his contract ended on July 19. E-Sens is no longer an artist under our label. We have parted ways because our ways of thinking about music are different."

Little else is known about the split, but many speculated that tensions between the company and the rapper may have been high in the wake of E-Sens's legal issues.

But "You Can't Control Me" suggests that the decision to leave Amoeba Culture may not have been entirely mutual.

Shortly after the song's release the agency gave a quick response to the media stating, "We were just finishing up Dynamic Duo's new music video. We heard about the song through the news, but we haven't actually listened to it yet."

As for how they plan to handle the situation, Amoeba Culture said, "It's something we will have to discuss after we get the staff together. We will decide the next step after we listen to the song."
