KPop Demon Hunters and Other Memetic Things
I've convinced myself that KPDH succeeds because it blends many styles effortlessly. I haven't seen it yet (I will tomorrow at the Sing Along though o_O), but I've heard the music a lot.
Like A LOT a lot.
It's good, but it's good because they've tricked you. Yes, even you were tricked, savviest reader.
Your Brain On "The Classics"
That whistling in Soda Pop? Yes, it's probably meant to evoke that dancing old guy from the theme park commercial. You liked that, so we command you to like this.
There are loads of these little "almost but not quite" similarities sprinkled throughout. There's also "pop sentimentality" to which almost everyone has susceptibility.
That harmonious hit in This is What it Sounds Like is calibrated. I'm convinced of it. They did warn us right there in the title. We were all too distracted by the lovely animation to notice.
Lighting In A Bottle
I don't know that anyone will hit this combination of things ever again, but they probably won't be able to play the trick twice. We'll see, I guess.
I'll be there for it, though. They got one thing right for certain: that is, indeed, How It's Done (done done).
