BBC - Culture - Can data reveal the saddest number one song ever?
Data journalist Miriam Quick put Spotify’s new algorithm to the test, analysing over 1000 tracks to find the saddest pop songs to top the charts. The results were surprising. he streaming service has collected metadata on each of 35 million songs in their database, accessible through their web API, that includes a valence score for every track, from 0 to 1. “Tracks with high valence sound more positive (eg happy, cheerful, euphoric), while tracks with low valence sound more negative (eg sad, depressed, angry)”, according to Spotify. There are similar scores for other parameters including energy (how “fast, loud and noisy” a track is) and danceability, which is exactly what it sounds like.

Framing Risk with Numbers: The Framing Effects of Risk Assertions and Number Formats on Emotions and Risk Perceptions: Mass Communication and Society: Vol 0, No ja
This study examines how risk assertions and relevant statistics presented in different number formats interact to influence emotional and cognitive outcomes. Experimental news stories presented risk assertions highlighting either safety from or vulnerability to violent crime, accompanied by crime statistics in absolute frequency, simple fraction or percentage format. Though it may be tempting to assume that large numbers such as national statistics in absolute frequency create a greater impression due to their sheer size, our results show that only probability formats including simple fraction and percentages resonate with assertions in generating emotions. Furthermore, we found that negative emotions play a mediating role in producing pessimistic risk assessments. Our findings reveal how people process numerical information and its impact on emotional and cognitive responses. Empirical and methodological implications for framing research, as well as cognitive aspects in emotional reactions and the nature of emotional effects on risk perceptions are discussed.
