I like this this entry on Gizmodo, written by furniture-fucker Adam Frucci, which points to a British High Court decision that that Pink Floyd's contract with EMI prohibits individual songs from their albums being sold individually.
I'm not usually one to cheer limitations on online (sold or otherwise) media, but I do cheer anytime people will choose to PAY for Pink Floyd music and are actually forced to, you know, listen to the whole album, as people were expected to in the 70s. Get with the program -- you don't just watch the Star Gate sequence from 2001: A Space Odyssey and get to call yourself a Kubrick fan (or know what the hell you're talking about in any context).
From the BBC News article (linked to from the Gizmodo entry):
In court, Chancellor Sir Andrew Morritt said the contract contained a clause to "preserve the artistic integrity of the albums".I have no sympathy for people who are as a matter of course willing to pay the iTunes- / record company- tax just so they so they can get "Another Brick in the Wall" or "Comfortably Numb" tracks without having (getting to) listen to the entirety of "The Wall" album. Fuck 'em. I say: "Let them crash."
On the other hand, those that care about the quality of the overall piece will get it (for free) as a full-album torrent anyway, so I'm not sure what they're worried about. (GASP..! could it be money?)
