The conglomerate’s music division doesn’t represent much more than a footnote in its overall financial picture, but in the last quarter, it was at least a positive footnote. Sales were up two percent–seven percent if you cancel out currency fluctuations–and operating profit was up 8.2 percent.

Hard to argue that this uptick will be sustainable, though. Sony (SNE) says the boost came from a couple individual success stories that will be hard to repeat, for obvious reasons: People bought lots of copies of the soundtrack to “This Is It,” the Michael Jackson concert movie, as well as the debut album from cultural oddity/viral video favorite Susan Boyle.

Looking for more traditional music business news? I can oblige: Music industry types tell me they’re freaked out that physical sales could take another steep tumble this year if retailers like Wal-Mart (WMT) and Best Buy (BBY) shrink the tiny amount of floorspace they devote to CDs yet again. And they’re also worried that digital sales are finally flattening out.

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.
