A study of 500,000 songs released (发行) in the UK between 1985 and 2015 showed that pop music had decreased in happiness and increased in sadness.
In a report published in the journal Royal Society Open Science, researchers at the University of California examined hundreds of thousands of songs and classified them by their mood.“‘Happiness’ is going down, ‘sadness’ is going up, and at the same time, the songs are becoming more ‘danceable’ and more ‘party-like’，” co-author Natalia L．Komarova told The Associated Press.
The study found songs in 2014 like Stay With Me by Sam Smith, Whispers by Passenger and Unmissable by Gorgon City have a “low happiness” trend.However, tracks from 1984 like Glory Days by Bruce Springsteen, Would I Lie To You? by Eurythmics and Freedom by Wham! had a“ high happiness” trend.“The public seems to prefer happier songs, even though more and more unhappy songs are being released each year，” the researchers wrote.
Apart from the emotional trends, researchers discovered that dances and pop were the most successful styles of music and that there was a “clear downward” trend, with the popularity of rock beginning in the early 2000s.“So it looks like, while the overall mood is becoming less happy, people seem to want to forget it all and dance，” Komarova wrote in an email.
It was also found that the “maleness” of songs—the frequency of male singers in popular music—had decreased during the last 30 years.“Successful songs are characterised by a larger percentage of female artists compared to all songs，” they wrote.
This discovery appears at a time when the conversation around sex equality in the music industry is at its height, with more male artists and songwriters.
