New Jay-Z tune a real ‘pop’ track

It’s a hip-hop homage to his favorite new girl.

First-time pop Jay-Z yesterday released a touching new tune for baby daughter Blue Ivy Carter that features her newborn cries — and also reveals the heartbreak he and songstress wife Beyoncé suffered over a previous miscarriage.

“Glory feat. B.I.C.,” describes the “tragic” ordeal the music super couple went through before their baby’s joyous birth at Lenox Hill Hospital on the Upper East Side Saturday night.

“Last time the miscarriage was so tragic,” Jay-Z raps in the tune released on his Web site, Lifeandtimes.com.

“We was afraid you’d disappear but nah baby, you magic.”

Blue Ivy stars in the hip-hop homage to herself. Jay-Z splices in a recording of her crying toward the end.

Brooklyn-native Jay-Z, born Shawn Corey Carter, vows in the tune to make Blue a happy little girl — in contrast to his own troubled childhood, which was marred by the departure of his dad, Adnes Reeves.

Reeves walked out on the family when Jay-Z was 11, the rap icon sings.

But the pain caused by an absent pop and the miscarriage were wiped out, Jay-Z sings, after hearing Blue’s first heartbeat.

The rap star hinted that Baby Blue was conceived in the City of Light.

Beyoncé and Jay-Z were spotted in Paris in April.

But while the emotional song may win over even Jay-Z’s harshest critics, Blue Ivy Carter is becoming known as Notorious B.I.C. to some following the hoopla her parents stirred up over her birth.

Other new parents at Lenox Hill say their intensive-care newborns were left in danger after their ward’s security cameras were taped over to give the power couple privacy.

Babies in the hospital’s regular maternity ward are routinely tagged with sensors that trigger security if one is moved where he shouldn’t be.

But infants in the neonatal intensive care unit, who shared Beyoncé’s delivery floor, aren’t tagged because the sensors interfere with medical equipment, said Rozz Coulon, whose twin daughters had been in the NICU since their premature birth Dec. 28.

“The cameras are there so people don’t take our children,” she said. “So when your kids already don’t have the security sensors, and the cameras are covered up with tape, it’s very alarming.”

Coulon said a swarm of earpiece-sporting private security guards also were milling around.

They were wearing tags that read “Special Event,” she said.

At one point, Beyoncé’s team resorted to flat-out lying to worried parents who asked what was going on, Coulon said.

“We were trying to leave, and the guys in black said we had to wait 15 minutes because they were ‘transporting hazardous materials,’ ” she said.

When the mom then pressed him on why such material would be on a floor full of babies, the guard backpedaled.

“He changed his story and said, ‘Oh, I meant they’re on a different floor,’ ” she recalled.

Minutes later, a large entourage was ushered toward Beyoncé’s wing.

NICU moms on their way to breast-feeding classes, which were being held just on the other side of Beyoncé’s private wing on their floor, had to get in an elevator with their newborn babies — a security no-no at most hospitals — and take it down, transfer to another elevator bank and ride back up to avoid Beyoncé’s area.

Lenox Hill Executive Director Frank Danza yesterday released a statement saying the hospital had not heard any complaints from patients.

Danza also said “no security plan” put in place by the hospital or Jay-Z “would have prevented or delayed families from gaining access to the NICU.”

That’s a crock, said new dad Edgar Ramirez, 25, whose daughter, Charlotte, was born by C-section on Saturday night.

“I wasn’t able to see my baby girl for three hours after she was born” because of a Beyoncé-related security “lockdown,’’ he said. “It was just ridiculous. I was so angry!

“They were blocking the elevators, all the windows were blacked out, there was security everywhere, they taking people off floors.”

Coulon and other parents are mulling legal action, she said.

Before the birth of Blue Ivy, her parents had reserved about a dozen rooms for her delivery and completely renovated them — including installing bulletproof doors and glass, sources have said
