We're Getting Sadder (Or At Least Our Popular Music Is)

“Over the last few decades, popular songs have switched from major to minor keys: In the 1960s, 85 percent of the songs were written in a major key, compared with only about 40 percent of them now. Broadly speaking, the sound has shifted from bright and happy to something more complicated.”
Researchers E. Glenn Schellenberg and Christian von Scheve studied songs from the past fifty years of Billboard’s Hot 100 charts and have determined that we’re growing ever more miserable as a society. (Or not. I could easily believe that an affinity for sad songs indicates a happier state of mind. And I think comparative analysis of something as vague and wide-ranging societal happiness at different times in history is specious to begin with. But fun to think about!)
