Going back to Infosnack’s mission statement of finding interesting data and commenting on it, here’s a great graph. Correlation does not imply causation, or does it? Did the decline in US lower 48 oil production really cause a decline in the quality of rock music?
Hat tip to Overthinking It, the blog that takes pop culture and then analyzes the crap out of it. They’ve got a great write-up over there about how the Rolling Stone top 500 list tends to reward early music rather than the best in the genre. He cites Green Day’s Dookie as an example. Now, I like me some Dookie, but compared to most of the stuff on the list I would say the list has it right.
