Pop song lyrics use more negative words (“hate”, “sorrow”) than 50 years ago
The use of words related to negative emotions has increased by more than one third…. If we assume an average of 300 words per song, every year there are 30,000 words in the lyrics of the [Billboard] top-100 hits. In 1965, around 450 of these words were associated with negative emotions, whereas in 2015 their number was above 700. Meanwhile, words associated with positive emotions decreased in the same time period.
