When it comes to music, we’re in the age of abundance. It’s everywhere.

How to sort the ocean and find what you like? Well, you could try Pandora. It’s an online music site that has x-rayed mountains of music. Tell it what you like, it’ll play you a lot more you might like.

Punch in Lady Gaga and you get Shakira. Punch in Stan Getz or Aaron Copeland or Springsteen — and Pandora gives you more in each vein. And maybe some surprises.

Friends used to recommend music. Now the web does. And it’s cool.

This hour, On Point: We’ll talk with the founder of Pandora about the future of music online.

Who knew mammograms and Pap smears could headline a week? But here they are this week, shoved into the health care debate just as everything is on the line for reform.

We’ve got the president in China, where the U.S. no longer towers. 9/11 trials coming to New York. The Fed chief warning of another year of high unemployment. Crunch time in the Senate on health care.

And women. Sarah Palin in the news. Oprah, signing off for cable. Hillary Clinton, in Kabul for Hamid Karzai’s inauguration.

Twenty-one year old Joe Cada won the World Series of Poker and $8.5 million last week in Las Vegas. A heck of a pot for the youngest winner ever.

But fully of a piece, says my guest today, with poker’s fabled place in American history. And in American culture.

Presidents, generals, gangsters, cowboys — and now millions of Americans online — have embraced the part-Puritan, part go-for-it gambler ethos of poker. A new history tells the story.

This hour, On Point: The tangled American roots of poker. And we’ll hear from the 21-year-old who won it all.

For a century and more, newspapers made money hand over fist. Then came the Internet.

Now, newspapers are dying. And news giant Rupert Murdoch is getting mad. He’s ready to fight.

Murdoch’s target is the biggest kid on the Internet block: Google. The News Corp chief says Google has essentially been stealing the news from companies like his and giving it away for free. It’s got to stop, he says.

Is Murdoch just blowing smoke?

The great novelist and short story writer Vladimir Nabokov emigrated to the United States, made his fortune with the publication of the incendiary “Lolita,” and then decamped to a hotel in Switzerland for the rest of his life.

He died in 1977, leaving behind — on 138 handwritten index cards — the fragments of a final book titled “The Original of Laura.” He wanted it destroyed. His wife, who once saved “Lolita” from the flames, declined.

Now, it’s out. Nabokov’s last work, published against his dying wish.

This hour, On Point: from the fragments of a master, Vladimir Nabokov’s “The Original of Laura.”

For years and years, the word to American women was: Get your mammogram. Self-examine for breast cancer. Be alert. Save your life.

This week, a new message. On Monday, an independent government panel of doctors and health professionals released a new report on breast cancer screening, reversing advice American woman have heard for decades.

Now, if you’re under 50, without special risk factors, no routine mammograms, they said. If you’re over 50, just once every two years. And those breast self-exams you were told to do — never mind. No need to teach that.

The new view is rocking boats all over the place, and drawing fiery pushback — in the midst of a national healthcare debate and cost-cutting pressures.

This hour, On Point: We’ll talk with the chair of the panel and ardent critics of the new view on mammograms.

Iraq combat veteran and Marine Staff Sergeant Jeremiah Workman went into some of the worst fighting in Fallujah. Nightmare stuff. Killed twenty men in a day.

He came out with the Navy Cross — and a brutal case of post-traumatic stress disorder, PTSD.

Now, from the brink of suicide and despair, he’s fought back to tell his story — and the story of many thousands of other veterans of Iraq and Afghanistan.

He’s fighting for acknowledgement of all that they bring home. All.

Sarah Palin’s new memoir, “Going Rogue,” is just out and already a bestseller. It’s in the bookstores today. She’s on Oprah. Her tour bus is hitting the road.

The book settles scores with McCain advisers the ex-Alaskan governor sees as having crimped her style on the vice-presidential campaign trail. Payback is the word. A little redemption, a little revenge. And a lot of stage-setting for whatever comes next.

Will she run for President in 2012? She’s not retreating, reports Sarah Palin. She’s reloading.

Brilliant tinkerers made the American economy. From Thomas Edison to Henry Ford to the Apple computer guys, late nights tinkering in the garage, the basement, the workshop changed the world.

In the late 20th century, big corporate R&D seemed to take over. Bright young Americans headed to Wall Street.

Now, a bunch of them are headed back to the garage. Tinkering again — this time turbocharged by new high-tech tools that put tinkering in high gear.

Could the next big thing, the economy’s turnaround, come out of your garage?

After eight years — on the run, in secret CIA prisons, being water-boarded, in Guantanamo — Khalid Sheikh Mohammed is headed to New York City.

The alleged Al Qaeda mastermind of the 9/11 attacks, and five others, will go on trial in lower Manhattan, “just blocks away from where the Twin Towers once stood,” said Attorney General Eric Holder on Friday.

It will be, without doubt, the trial of this young century. A vindication for American justice, say some. A circus and a threat, say others.

Novelist Jonathan Safran Foer made his name young and powerfully.

In two startlingly fresh books — “Everything Is Illuminated” and “Extremely Loud and Incredibly Close” — he brought a new generation’s eye to the Holocaust and to the shock of 9/11.

Now, the young novelist has gone non-fiction to look at the most elemental of human habits: what we eat. Specifically, the factory-farmed meat Americans consume in titanic volumes.

He thinks it’s wrong. He may persuade you.

President Obama, on his way to a week in Asia today. A quick stop in Alaska, then Tokyo, Singapore, Shanghai, Beijing, and Seoul, South Korea.

Every stop has its agenda. Bucking up old allies. Talking trade, military bases, America’s commitment in the Pacific.

And at the heart of it all, Washington’s dance with China. Our “vital partner and competitor,” as the president calls it.

Obama will be face to face with China’s top leaders. They build, we buy. They lend, we borrow. It’s a giant relationship at the heart of the world economy.

A year ago, with a giant economic stimulus package in the works, many Americans envisioned a rebuilt nation. Infrastructure. Bridges. Green cities.

It hasn’t exactly happened. But the design of all that surrounds us — all that’s built, old and new — is a daily message to us about who we are and what we aspire to.

Pulitzer Prize-winning critic Paul Goldberger wants to remind us of why architecture matters, in shaping lives and cultures. From ancient Rome to the next wave of American — or Asian — building.

The H1N1 virus is more commonly known as “swine flu.” That doesn’t mean you can catch it from a pig, but it does point to the source of the infection.

And it’s far from the only disease that can make the jump to humans from other species. Avian flu. Rabies. Ringworm. Hantavirus. West Nile Virus. Even Ebola and HIV likely originated in animals and made the leap.

Now, with the world a global village and populations soaring, experts warn these species-hopping diseases may arise more frequently, and become more dangerous.

Flags at half mast across the country. Thirteen dead, many more wounded — shot in cold blood at the Army’s Fort Hood in Central Texas on Thursday.

The alleged gunman — a military psychiatrist, an American Muslim, one of the Army’s own — faced deployment to a war he opposed.

The Army’s Chief of Staff calls it a “kick in the gut” — and warns of backlash against Muslim-American troops. Unanswered questions abound — about the shooter, the warning signs, mental health in the ranks, an Army stretched thin.
