Classical Radio Broadcasts iTunes for the Vinyl Generation

I knew that major orchestras, including the NY Philharmonic, are offering downloads of live concerts on iTunes. But this morning was the first time I heard such a download played on a classical music radio station. Maybe this is old news, but it’s the first time I’ve noticed it, and I listen a lot.
This morning, New York’s WQXR played the Beethoven Seventh, with Esa-Pekka Salonen conducting the LA Philharmonic. There are those (I’m one of them) who think that CDs represent a loss of sound quality from vinyl. What about digital downloads?
Clicking the “Buy CD” link on WQXR’s website playlist (see 10:05 a.m.) takes you to a long list of recordings of the Beethoven Seventh, but none by Salonen and none by the LA Philharmonic. That’s because there IS no CD of this performance; it exists only on iTunes. Shouldn’t WQXR’s website provide THAT link?
The classical music audience skews old. Soon everything is going to be download-only. Does anyone see a problem here?
The good news is that iTunes can possibly help change those demographics, so that maybe the classical music era won’t come to an end, as Greg Sandow fears. My daughter, more Nickelback than Bach, does have Mozart on her iPod. Maybe I should find out the rest of her picks and publish Joyce‘s Classical Playlist!
