I won't address the larger philosophical questions relating to common culture because I'm not really qualified to do so.
I do have a certain amount of ambivalence about the current state of music retailing. This is one reason I won't use streaming as the sole way listen to music that interests me. I'll stream it once or twice, and if I'm going to do more than that I'll buy the disk or at least the download. I feel for people who are trying to make a living in "content creation" in the modern age, since the content is the first thing that is made into a cheap commodity that can no longer pay a living wage except to the very lucky.
On the other hand, I don't feel a lot of sympathy (necessarily) to the large media companies. I can't count the number of times I would have liked to buy record A, B or C only to have it be out of print, or only available as an expensive import, or even only available for download in (say) France but not the U.S., all for seemingly arbitrary reasons. I wonder what the real overhead is to the companies that own the content to make the digital masters (and pdfs of the liners) available at the various download services. They don't even have to host the files or the network bandwidth. They just need to allow me to pay to download them. And yet things still go "out of print". This confuses me, but I figure I just must not understand something about how the industry works.
