If a given fact is relatively new, I would expect (and forgive) search results to not necessarily reflect that.
But in this case we're talking about ~40 year old song. The reddit thread mentioned in the article is 10 months old.
I've also checked this logged in and incognito and get consistent (and seemingly correct) answers.
So what are we left with? Is the author in some experiment giving bad results? Were there bad results that got corrected between the time of writing and now? Did some Google search quality engineer see this and correct it?
All of these seem like a stretch. I'm perfectly willing to entertain the idea that Google has become worse but there are rarely conrete examples. It all just comes down to vibes. And when there are examples (as per this post), it doesn't match my experience. Can I really be that lucky? That seems to stretch credulity.
Probably the most egregious example of bad search results I've personally seen is how an astroturfed propaganda site was the top result for the Armenian genocide for literally years [1].
