Jupiter Research has done some prognosticatin' and come to the conclusion that digital sales are going to keep on growing. In fact, if predictions hold true, digital sales will grow at a compounded rate of 16% per year, to a total of 2.5 billion dollars, or just over 22% of total US consumer spending on music.

Glenn Coolfer astutely observes, "Before you do any math, read a blog post about the survey by Jupiter analyst David Card. He explains something the press release does not: Jupiter did not count ringtone sales as digital revenues. He wrote, "Digital music sales will total 22 percent of US consumer music spending in 2011, and ring tones another 12 percent." Combined with download spending, the adjusted digital figure is actually 34%. That leaves the CD with about 66% of the market."

Subscription services are forecast to keep growing as well, with a staggering 32% compounded growth rate in just that category alone. Napster must be salivating but, frankly I don't see it. Unless some major shift comes along and changes the subscription landscape, or the Major labels relent to an eMusic style model, I just don't see how 32% growth in subscriptions is remotely possible.
