The two plots in the left column show the magnitude of year over year change in the average relative novelty score as songs are compared to later release years.

The vertical lines indicate the inflection points where this occurs, which for MIR relative novelty is after two years, and for lyric relative novelty is after 3 years. The plot in the right column shows the distributions of relative novelty change for MIR novelty, and lyric novelty, which are calculated by taking the average change in relative novelty which occurred in the first three years after the song’s release
