Also relates to Dwight Howard reference one line prior to this. Price Hakeem/Akeem helped the Rockets recruit Dwight Howard to the Houston Rockets. Hakeem the Dream Olajuwon was the great Rockets center in the 80’s and 90’s. Note Prince “H"akeem won two championships in 1994-95

After the release of Brown Sugar in July 1995, D'Angelo lost inspiration and succumbed to writer’s block and went into a four and a half year hiatus. After finally nailing a sound, D'Angelo is finally ready to be heard once more.

Similarly after the release of Voodoo, D'Angelo would go 14 years without a solo album until Black Messiah in December 2014.

Chris Hansen is a television journalist best known for being in Dateline NBC’s “To Catch a Predator” where sting operations to catch sexual predators lurking the internet would set be up with Hansen coming out to confront them. Pusha pops up similarly at the home of someone that owes him money.

This could also be a reference to his group Clipse’s 2006 track “Chinese New Year” where the chorus says:

I’m at your door
Your eyes are like ‘Why are you here?’

Scarface, the favorite movie of many an emcee, is the story of ambitious Cuban immgrant Tony Montana who rises from being penniless to an extremely wealthy criminal drug lord. However, Kendrick actually discusses the tragic ending of the film, which not a lot of rappers seem to do.

In the end, Tony loses his wife, sister and best friend, his enterprises being closed one by one and his enemies storm his mansion and gun him down. People get so caught up in the glamorous aspects of criminal activity (and the film) that they overlook its dire consequences.
