Now, back to our regularly scheduled programming: I’m seeing more and more evidence that Apple (AAPL) notwithstanding, the industry’s last few months were bad even by the industry’s own terrible standards.

Earlier this week, a music industry exec told me he thinks that the CD sales decline, which started nearly a decade ago, accelerated at the end of 2008: “[Retail] floor space shrank even more, [unsold CDs] came back even faster, everything got worse, faster,” he told me.

The newest data point: Awful results from Sony’s (SNE) third-quarter earnings report, which covers the last three months of 2008. The company’s Sony Music Entertainment label saw sales shrink 22 percent compared to the previous year due to the “accelerated decline in the worldwide physical music market resulting from the worldwide economic slowdown.”

It’s possible that we’ll see a bit of variation in results from the other big music labels–EMI Music Group, Vivendi’s Universal Music Group, and Warner Music Group (WMG)–based on the makeup of their artist rosters, etc. But the worrisome thing is that Sony’s arsenal included three of last year’s biggest stars: AC/DC, Beyoncé and Britney Spears.

So while it’s possible that Warner Music, which reports next Thursday, won’t have equally brutal results, it’s a fair bet that it will.

Sort-of-related point: If you have a couple minutes and are interested at all about what the music business might look like in the near future, check out this New Yorker interview with Muxtape creator Justin Ouellette.

Ouellette achieved a brief bit of Internet celebrity last year when his free music-streaming site caught on with the the Web cognoscenti, but then folded after receiving complaints from the music labels’ trade group. Now he’s back with a legal version of the site, which will have much smaller ambitions.

Last June, a Vornado executive told Reuters that the store would shut down in the first quarter of 2009. The decision to close the store appears related to real estate and the value connected to the location. That executive was quoted as saying that Virgin pays only $54 per square-foot when the market rent in the area is about $700 a square foot.

So, while the store, which does an estimated $55 million in annual volume, is profitable to the tune of $6 million, according to sources, the space would be even more profitable for its owner with a higher rent tenant. Vornado bought the 180,000 square foot retail component of the Bertelsmann building, which houses the Times Square store, in 2006, and will lease the space to Century 21, according to reports.

The closure leaves the Virgin chain with five stores, and one of them, the Union Square store in New York, will now be the city’s premiere record store, with an estimated $40 million annual volume. But the status of that store is also at question as the Related Cos. and Vornado leased the ground floor of the store to Nordstrom Rack for the holiday season, only to have the deal fall through.”

I get that the decision appears to be “related to real estate,” but it’s really about the health–or lack thereof–of bricks-and-mortar music retail. If the No. 1 store in the country can’t make it, and if New York City’s “premiere record store” rented out a floor during the peak sales season, then why is anyone bothering to sell CDs in stores, period?

Plenty of retail executives seem to be asking themselves the same question, and are responding by cutting the small space they’ve devoted to CDs even further. The exceptions: Special promotions for exclusive albums, like Wal-Mart’s (WMT) successful push for the new AC/DC album last year, and Best Buy’s (BBY) unsuccessful gambit with Guns N’ Roses.

Latest example: Borders Group (BGP), the struggling book chain, has cut its music inventory by 30 percent in the last year, the company said. Music now occupies about seven percent of its floorspace, and the space it used to take up has been given over to higher-margin products like children’s books.

Borders makes up a relatively small portion of U.S. music sales, but most big retailers have been doing the same thing for more than a year. If you don’t believe me, try to find the CD section next time you visit a Target (TGT) or Best Buy (BBY) this month.

The big stores will embrace individual albums–if they have an exclusive, like Best Buy’s deal with Guns N’ Roses, or Wal-Mart’s (WMT) recent AC/DC promotion. (That’s Best Buy’s GNR promotion, pictured above. Lonely, isn’t it?) But beyond that, they are basically telling music shoppers, who bought some $7 billion worth of discs last year, to take their business elsewhere.

Did you buy the “Only by the Night,” the newish album from Kings of Leon? If so, Sony would like to thank you.

Everyone else, though, is going to have to pick up the pace or Sony’s new investment in its music business isn’t going to pay out.

Footnoted in Sony’s Q2 earnings release today are the details on the performance of Sony BMG, the music label it used to own in conjunction with Bertelsmann AG.

This summer Sony (SNE) bought out its partner for $900 million and now owns the label outright.

But the newest results make it hard to understand why it made the investment: Sales dropped 11 percent, to $762 million, and the company lost $57 million, up from an $8 million loss a year ago.

Those results aren’t out of the ordinary for the label, which has been struggling along with the rest of the industry for many years.

The now-boilerplate language to describe the results blamed the “continued decline in the worldwide physical music market not being offset by growth in digital product sales.”

Okay. So what about the Kings of Leon? MediaMemo confesses that it has yet to hear the new album, but Sony says it one of the best performers of the quarter.

Other winners: AC/DC’s “No Bull,” which MediaMemo believes is actually a concert DVD, and “One Chance” by Potts, which I’ll confess I’ve never heard of, period.
