Description:
The audio features liveness and instrumentalness were removed because their Kaiser–Meyer–Olkin (KMO) values were lower than 0.5. We ran a PCA on the resulting audio features (acousticness, danceability, energy, loudness, speechiness, tempo and valence). Bartlett's test (p < 0.001) and the Kaiser–Meyer–Olkin (KMO = 0.61) measure verified the sampling adequacy for the analysis (all KMO values for the individual features were above 0.5). The scree plot indicated a solution with two factors, and there were only two PCA components with an eigenvalue larger than 1, which explained 56.25% of the variance. Thus, we accepted this two-component solution and computed the corresponding PCA scores for each component (figure 4).

Description:
We ran a PCA on the same audio features used in the main analysis (acousticness, danceability, energy, loudness, speechiness, tempo and valence). Bartlett's test (p < 0.001) and the Kaiser–Meyer–Olkin (KMO = 0.63) measure verified the sampling adequacy for the analysis (all KMO values for the individual features were above 0.5). The scree plot indicated a solution with two factors and there were only two PCA components with an eigenvalue larger than 1, which explained 57.66% of the variance. Thus, we accepted this two-component solution and computed the corresponding PCA scores for each component (figure 5).
