Vienna – People sometimes listen to music to express and regulate their mood. According to a study, this can be seen not only on an individual level, but also on a societal level. Over a 50-year period, stress levels and negative emotions in popular song lyrics rose almost consistently, the journal says Nature. In times of crisis, however, it is the other way around. To do this, a team of researchers with participation from Vienna analyzed 20,186 songs.
