Table 1.
Correlations with average lyrical compressibility.
Fig 1.
Change in lyrical compressibility, along with a music production-based forecast for future lyrical compressibility from regression with ARMIA (1,0,0) and index of novel song choices as an exogenous predictor.
Light purple indicates 95% confidence bands, dark purple indicates 80% confidence bands.
Table 2.
Partial correlations between novel music production index and average lyrical compressibility.
Fig 2.
Relationship between lyrical compressibility and chart position for years differing in music production volume.
Confidence bands indicate 95% around the estimate.
