It's now a truism, or a cliche, to mention how the "On-Demand" economy is eating the world of personal services (Uber, Lyft, AirBnB, Task Rabbit, Postmates, Instacart and dozens of others). Among a bunch of other reasons, millennials don't want to own things in the same way that we, their parents, did/do. What is lesser remarked, but equally disruptive to a huge market, is that, as noted here in the Financial Times, the "On Demand" business model is also eating the music world - streaming has now outpaced downloads, with disruptive repercussions for an already beleaguered industry.
