Apple surely can see the complete catalog of The Who that I have in my library, including the vinyl albums that I've ripped. Not that the Music app could see it, but Apple could also see the eye-watering amounts of money we've spent on tickets to watch 75 year old men prance around on stage (via the tickets from the last three tours in Wallet).
So what's the first song played on this new Discovery station? "Who Are You?" by...wait for it...The Who. Whether you're a Who fan or not, is there anyone walking this planet over the age of 21 that hasn't heard that song?
Solid state batteries get here when they get here, and ignore the hype. Over the decades I don't recall that I've ever heard a breathless battery announcement that's going to change the world, and then had that battery technology pan out when scaled to industrial levels. IOW, yeah, I'll believe it when I see it.
Buy what you need today, otherwise you're likely to "wait 3-4 years" and then, oops, those batteries are still five years away (as they always seem to be) and now you've waited nine years while driving a twenty (well, closer to thirty now) year old car.
