I've noticed a thing about the YouTube recommendation algorithm.
I had heard about the new Beyoncé single Texas Hold 'Em, so I searched for it on YouTube so I can listen to it. Subsequently, it started proposing to me various dance videos that people had made to that song. Perfectly reasonable. I watched several of those too. Then I got bored and wandered off.
After that, I noticed that the YouTube algorithm was absolutely convinced I wanted to see completely random videos that happened to use Beyoncé's Texas Hold 'Em as background music.
Which, yes, is the way that machine learning often fails: it gloms on to some detail, fails to note any sort of context bc it doesn't *do* context, and concludes that's the relevant detail to optimize for.
It was a pretty striking example, and suddenly I realized: this is not the first time. Until this happened, I hadn't noticed, but YouTube's recommendation algorithm will often show me video after video with the same *background music*.

For instance, I noticed a while back that umpteen zillion random shorts wound up in my feed that all had Jain's Makeba as the soundtrack. I had just thought it was wildly popular, because it is indeed a super catchy bop.
In retrospect I think maybe what happened was that the YouTube algorithm noticed I – entirely coincidentally – watched all the way through two random videos which happened to use the same soundtrack, and concluded what I like to see is videos that use that song.
Same thing happened with Paris Paloma's Labour. And the Longest Johns' Wellerman. And some group of basses singing Hoist the Colors (which, delightfully appropriately, resulted in a stream full of 100% unadulterated thalassophobic naval architecture porn.)
