Gaga just released the following note about her upcoming album release "ARTPOP". I know Bjork did something similar with her last release. I suspect this will become more and more common not only because we live in a multimedia world with easy access to portable devices, but also as a way of encouraging multiple sales of the same material. It has a lot of interesting potential though, particularly if the extra elements are not just independent add-ons but contribute to the experience of the music itself. What do you think of the concept of a multimedia release for music?
