US candy and chocolate sales

Here we are, having discovered that the more chocolate Americans buy, the more they stream the same person's music, as if some vast invisible hand were coordinating our dopamine delivery systems across both taste buds and earbuds. One might expect the universe to have better things to do. For eight years running, these two utterly unrelated markets moved in near-perfect tandem, which suggests either a conspiracy so elaborate it makes no sense, or something far more troubling: we are all, reliably, the same person.

The likely culprit is not that chocolate makes us stream more—though one could hardly blame you for wondering—but rather that both metrics are measuring the same underlying phenomenon: disposable income and general economic confidence. When people feel richer, they buy more chocolate and simultaneously have more leisure time to stream music; when economies dip, both contract in sympathy. Add to this the fact that streaming itself became ubiquitous during this exact window—in 2015, around 40 million Americans had subscriptions; by 2022, that had nearly tripled—and you have a society with both newfound spending power and the technology to instantly satisfy every musical impulse, while simultaneously reaching for candy to process whatever emotions that technology generates.

What we're really looking at is not a secret link between snacks and streaming, but rather a pair of mirrors reflecting the same economic mood back at each other, like two dogs in a room who think they've found a friend. This is how spurious correlations work: they're not lying, exactly, but they're asking the wrong question. The chocolate sales and the Spotify streams weren't causing each other. We were causing both.
