This is another reality of search results and digital entropy to reckon with. Across different search terms, this is a problem caused by targeted SEO as much as it is simply self-optimizing/biasing results and indirect consequence. Some time ago I went hunting on YouTube for 1980s synthesizer stock music, and not entirely surprising over 95% of the search results were modern "synthwave" tracks from the past few years, riding on the trend of labeling itself as "1980s". Because of the explosive popularity of the "synthwave" genre it was next to impossible to find what I really wanted. Just 6-7 years ago the search results were quite accurate.
