SEA 1,250 vs 3,750 Stream Split

Under Billboard / Luminate formula (instituted mid-2018), 1,250 on-demand subscription streams equal one album unit, while 3,750 ad-supported / programmed streams equal one unit. This prevents free streaming inflation.

TEA (Track Equivalent Album)

Ten individual track purchases count as 1 Track Equivalent Album unit. As digital downloads decline in favor of streaming, TEA typically represents 1% to 5% of modern album consumption.

Longevity Decay Curve

Catalog powerhouses (like Stick Season, SOS, or Fleetwood Mac's Rumours) exhibit low weekly decay (1–4%), stabilizing at 20k–40k units/week for years, whereas front-loaded rap or pop debuts often drop 40–60% by week 2.
