The Timeline

1900 to 2026. Each band is a genre, as thick as the number of works tagged with it that year (3-year average; a work with two genres counts in both). Above it, 568 styles are pinned at the year they took off — the first year they reached a tenth of their peak. It opens on the 1940s — scroll left for the thin early decades, right to 2026.

The 1950s bulge is part history (the LP) and part catalogue: Discogs coverage turns dense around then, so many older styles are first counted there.
