It’s tough for hip-hop stars to age well. Once they become celebrities living in mansions and starring in family movies, street cred is usually the first thing to go. Just ask Ice Cube. Longevity just wasn’t built into the hip-hop lifestyle, with its premium on youthful swagger, street tales and fast turnover. 

But Jay-Z, who turns 40 in December, asserts that he’s the exception on his 11th studio album, “The Blueprint 3” (Roc Nation), which he rush-released Tuesday after it leaked on-line. In hip-hop, extreme wealth is more potent than any drug, more lethal than any Glock – or so Jay-Z says.

  “I’m a multimillionaire, so how is it I’m still the hardest [guy] here,” he announces on “D.O.A. (The Death of Auto Tune).”

 The track takes a shot at the ubiquitous vocal effect that has dominated hip-hop production in recent years, though Jay-Z is not above using it himself elsewhere on the album. If nothing else, Jay-Z has proven himself an expert at knowing the marketplace, and “The Blueprint 3” employs a handful of top-dollar producers (Kanye West, Timbaland, Swizz Beatz, the Neptunes) to cover all the commercial bases, Auto-Tuned or not.

 Its reach echoes the first “Blueprint” album, released in 2001 and coproduced by West, at that time a relative unknown still three years away from making his star-making solo debut. The combination of West’s dusty soul grooves and Jay-Z’s determination to reassert his skills as a master MC (after a few years in the pop celebrity wilderness) turned the album into a landmark.

“Blueprint 2” came out a year later, but was a far less focused effort, larded with cameos, as if Jay-Z could only be intermittently bothered to participate in his own album.

“Blueprint 3” splits the difference between its two predecessors, with Jay-Z sounding hungrier than he has in years on about half the tracks while sharing time with guest stars or grappling with undercooked production on the rest. At its core, the album is less about introducing newfound skills or subject matter than it is a platform for Jay-Z to showcase his imperious flow, to reassert his world-conquering ego, to remind everyone just who the heck he is. Just as his New York predecessor Rakim made his menacing delivery sound almost off-hand, Jay-Z has a way of delivering the news as if he’s already done it all — twice.

Born Shawn Carter in 1969, he grew up a drug dealer in the Brooklyn housing projects. He turned to hip-hop as a way out, self-releasing his debut in 1996 when no label would take a chance on him and turning himself into a star and powerbroker. Last year Forbes magazine estimated his annual income at $82 million. Little wonder he once crowed, “I’m not a businessman, I’m a business, man.”

By celebrating his business as a more elevated (and legal) form of gang-banging, Jay-Z has turned himself into something of a rap godfather. But he’s been phoning it in lately; on his 2006 album “Kingdom Come” he sounded as though he would rather be hanging out on his yacht with Beyonce.  

“The Blueprint 3” aims to show everyone he’s still got wicked skills on the mike. It does, even as it also illustrates that sometimes he coasts on his celebrity. The opening “What We Talkin’ About” sets the tone: He doesn’t have time to escalate longstanding beefs with his rivals because, let’s face it, they’re just peons and he’s got more important things to do, like hang with his pal, the new U.S. president.

 Hubris reigns. He’s the king of New York, able to command cameos from Rihanna and Alicia Keys on “Run This Town” and “New York State of Mind,” respectively. These tracks are the sound of Jay-Z cruising for pop hits, and they already sound like anthems. But there’s no justifying “Forever Young,”  with a vocal hook sung by Mr. Hudson; it’s the kind of mush that suggests there might be something true to those rumors Jay-Z has gone soft. There’s the ponderous “Reminder,” a blustery list of accomplishments. And “Venus Vs. Mars” reaffirms that Jay-Z has never been particularly strong at seduction raps.

 Yet even at three-quarter speed, Jay-Z can still be formidable. Timbaland’s sci-fi production on “Off That” is a poor fit, but the MC opens up a spigot of rhymes about refusing to live in the past, invoking his nemesis Bill O’Reilly to comic effect. The hard-edged soul claps of “A Star is Born” and the zinging strings of “Already Home” (both produced by West) are natural fits, and he dazzles without breaking a sweat. He even turns a joke about his resemblance to a camel into an opportunity to once again disarm his critics. The message: Don’t mess with ol’ Gray-Z.
