The selling and buying also has very interesting implications on the music download market. If I buy a CD, I can sell it to other people or trade it for other CDs if I grow sick of it. If I buy a downloadable track, I can do nothing of the sort. I can't transfer the MP3s to a stranger even if I would be so kind and delete them on my own machine after the sale.
This is a very weird side-effect of the change that is happening to music, with the market going from selling real physical items that can be resold to selling something as ephemeral as a "download right". No more flea market vinyl sales, no more rare editions?
The future generations (and here's me sounding like my beard's much longer than it actually is) might not experience how there can be something physical related to piece of music. I love that stuff! If it's some special edition, I usually even remember the texture of the special paper they used in the CD booklet when I listen to the album.
Look at Chthonic's CDs! Those are masterpieces of packaging, each CD contains special collector cards, a set of pretty Taiwanese "prayer money" with some calligraphy on it or other amazing little gimmicks. The band said they like to do this because it improves sales of the original CD in Taiwan. Those special items are something the pirates can't be bothered to copy. Real, proper pirates that sell copied CDs, I mean.
I really hope something physical element and some way of resale and trade can remain alive, even though the survey answers so far point in a different direction
I'm very modern in almost all things, but I like my music reasonably old-fashioned, preferably on a CD and not mixed with so much loudness that it has all the dynamics of a dead duck.
