The article's premise is that the music industry is about to change due to the model that the movie industry uses called windowing, thus extracting the maximum dollars in order of one willing to pay the most for it up front.

What it fails to mention is that this practice by the movie industry is hated by he various consumers, and thus exacerbates the piracy problem. The difference between the movie and music industry is such that, movies are difficult to leak and the most widely used methods of leaking them typically don't carry high enough quality to be worth watching for most, thus the consumers oblige. For music, ripping full quality sound waves at ones liesure and releasing them is much easier. I'd suspect that introducing windowing into music will only exacerbate piracy during the most exclusive periods.
