Fig. 4: CDSongs are shown blue (n = 313), ADSongs in red (n = 267), and CDStories in green (n = 342).

A shows the relation between the log normalised number of YouTube views as a function of complexity (i.e., the Compression Ratio). B shows the Compression Ratio (total amount of information divided by length) across conditions. C shows the relative progression at which texts reach 25, 50, 75, 85 95% of their total information content. For instance, CDSongs reached 95% of their total information content later than ADSongs. D shows the probability of information input in segments. E shows the R2 values of the compressed size across conditions. F shows the standard deviation of the derivative of the compressed size. G shows the mean redundancy period duration in each song. H shows within-song redundancy period variability (std). Fig. SM3–5 shows the same analyses broken down into English, French, and Spanish corpora separately.
