The Nets' "authentic" new intro video features a (cleaned-up) Jay-Z song. Flashback to the 2012 intro video.

From a Brooklyn Nets email: 

Behind-the-Scenes of the Nets Open Video

On Opening Night, we unveiled a brand new open video. For those who haven’t attended an NBA game before, an open video plays on the jumbotron right before the starting lineup is announced. Its purpose is to get everyone in the building, from players to coaches to fans, excited about the game that is about to be played. “When people walk into an NBA arena to watch a game, you want them to feel the electricity of the environment they are in and the open video sets the tone for that,” said Noah Lau, content producer for the Nets.

For this year’s video, we wanted to create something inspired by Brooklyn. “Being in New York, we wanted to take the opportunity to make something that is really unique to our city,” said Lau. “A lot of teams do cool sets but they generally don’t do things that actually represent the city they play in.” The video is set to U Don’t Know by Brooklyn’s own Jay-Z. “Overall, we wanted the video to feel like Brooklyn. Authentic and raw. I’m proud that we did something that really represents us.” You can watch the video here or get the full experience in-arena at a Nets home game.

 

Well it's just an excerpt from "U Don't Know," Below is the excerpt, via Genius:

[Intro]
Turn my music high, high, high, higher
(You don't know what you're doin'— doin'— doin'—)
Sure, I do

[Verse 1]
I'm from the streets where the hood could swallow 'em and
Bullets'd follow 'em and
There's so much coke that you could run the slalom
And cops comb the shit top to bottom
And say that we are prone to violence, but it's home sweet home

The bolded words are blanked-out in the version above. See Genius for annotations and explanations.

Then, some of the outro, "Will not lose, ever," coupled with excerpts from a game announcement. 

Flashback, 2012

The team is the team but the personnel, of course, keeps changing. Now the featured players include Ben Simmons, Cam Thomas, Mikal Bridges, and Cam Johnson.

Back in 2012, with John Forte's catchy original "Brooklyn (Something to Lean On)" the featured players included Deron Williams, Kris Humphries, Joe Johnson, and Brook Lopez. The latter is still in the league, playing for the Milwaukee Bucks.

   

Here's a longer cut.
