I'd be lying if I said the J-pop scene was one of my active areas of interest, but this article caught my eye nonetheless. The physical CD is still king in Japan, which is bananas, but there does appear to be some movement (emphasis is my own):

Early 20-somethings and teenagers aren’t rushing out to buy CDs — they can’t afford to drop ¥3,000 too frequently — and they aren’t fixated on sound alone. Rather, they gravitate toward video-sharing sites such as YouTube and MixChannel, where users just like them can create their own dances and silly clips set to the music they like. Online, the listener holds the power.

Sharing and remixing content is a staple of the up-and-coming generation—a point that goes right over my head every time. What I would argue is “quality” media for us olds appears to have little or to no bearing on what is enjoyed by today's youth. Perhaps, like the young skateboarding twins, the effect of YouTube flattening and expanding our access to media has fundamentally changed how you feel your way through the world.

Music for older folks is precious, tightly held, an artefact. Music for the kids? It's a social canvas, just the beginning of something else. And, that seems like no big revelation... unless you can't make heads or tails of Snapchat.
