I'm on a prog forum so I'll be shot down here, but it just seems pretentious of them to not let their fans enjoy their work however they want in favour of a (less convenient) show of driving home what an awesome singular experience their albums are. Sure, I do personally think DSOTM should only be listened to in one go, but why should Pink Floyd force people to do so, regardless of how necessary they might think it is?
Also Orbert, I don't really agree with your book analogy, as you can still easily get enjoyment out of DSOTM as a casual listener by just putting on, say, Money, if you have a craving for it, which you can't really do with a random chapter from the middle of a book.
I'm against this move.
