Proof of concept. Only of tracks carry a genre label so far,
assigned by hand to the highest-volume artists. The grey unlabelled band is
everything still awaiting the classification pass — it is shown rather than hidden so
the shape of the gap stays visible. Treat trends as indicative of the method working,
not yet as findings.
Tracks added per period
Playlist length swings from 2 tracks (Jul 2020) to 120 (Dec 2021).
Thin periods make share figures unstable, which is why quarterly is the default view.
