For the first time in something like a decade, CD sales increased this past year. They're coming back, book it. I'm willing to bet SACDs become a big thing over the next few years as a large swath of listeners bail on vinyl due to cost, maintenance, space, and just general weariness at how much of a gamble and hassle the medium has become with plants as overworked and backed up as they now are.
And with so many streaming services fracturing the viewer and listener base I think a lot of younger people are starting to realize that maybe renting your media from giant corporations isn't the most sound model to rely on when it comes to the art you love. And they're going to start buying physical media again. And for the most part they don't have the space or the money for vinyl, so CDs it is.
