The Juniper Research paper on mobile music has been getting a lot of comment today (see SMSTextNews and MocoNews) and it's easy to see why. Reporting that the market in 4 years time for subscription music service will reach $3.5 billion for subscription services, and $2.8 billion for downloaded original content is sure to generate headlines. The honest truth is nobody knows what is going to happen with music. What we see today is not the market in six months time, let alone four years. Look at the game-changing Comes With Music program from Nokia. Whoever can guess the right landscape may make money, but for now, Research Firms doing big extrapolations are clearly delivering a profit.
