Emerging business mogul Jay-Z is back to doing what made him famous in the first place.

The rapper’s new song, titled “Open Letter,” addresses his controversial trip to Cuba with wife Beyoncé, as well his rumored decision to sell his stake in the Brooklyn Nets in order to pursue his own sports management company.

In the song, Jay-Z attacks the politicians who questioned the legality of his trip to Cuba with several biting verses.

"Politicians never did s--- for me/except lie to me, distort history," he says, adding that he “turned Havana into Atlanta.”

He even references his well-known friendship with President Barack Obama, implying that the trip has caused the commander-in-chief some controversy of his own. "Obama said, 'Chill you're going to get me impeached'/You don't need this s--- anyway, chill with me on the beach,” he raps.

Jay-Z also drops a few verses that discuss his decision to sell his share in the Brooklyn Nets in order to fund his new sports agency.

“I woulda moved the Nets to Brooklyn for free/except I made millions off you f------ dweebs/I still own the building, I’m still keeping my seats/You buy that b------, you better keep your receipts.”

The Huffington Post suggests that “Open Letter” is Jay-Z’s attempt at silencing his critics after maintaining a low-key persona during the 2012 presidential election. As key supporters and fundraisers for the Obama campaign, the rapper and Beyoncé were sure to avoid any bad publicity. Now that Obama is back in office, the superstar couple is free to take on their detractors.
