what an odd post, for this thread. must be the chart, that caught your eye.
I love me some data. And old skool rap.
My favorite chart was the "Profanity in Rap Over Time" where they analyzed the 5 most popular albums of each year with the peak being in 2001. I too thought Eminem would have been responsible for this, but none of his albums were included that year, or any year. Where Eminem did have a significant impact though was in the Homophobic Index - off the charts.
At least misogyny is on the way down.
On a Michigan Athletics message board I frequent (mgoblog.com), after every loss in the football season, someone compiles the number of times each curse word is used in the gameday thread and syncs it up with what the score was at any given time in a serious of graphs far more complex than this, actually. I'll try to find you an example.
Coincidentally, I've always thought you'd get a kick out of it but it seemed a bit of an esoteric leap to be like, "hey, smackie, come look at our swearing analysis," just on a lark.
