My research investigates the links between music listening, mood and mental health. I’m using the ‘Mood Music’ dataset collected at the University of Bristol, which consists of music streaming histories from Spotify, Ecological Momentary Assessment of mood, and mental health survey data. The music streaming data and time-sensitive mood data form two parallel time series, which is a novel combination of music and mood data allowing for causal analyses. I will investigate causal links between music and mood, how this may be influenced by personality or mental health, and other factors such as lyrical sentiment.
