Bilboard Has Changed The Math Behind The Hot 100 and Top 200 Album Chart

Billboard’s main singles chart, the Hot 100, which was already confusing because it has long included radio airplay data alongside sales figures, will continue to count streams on most platforms, but from July there’ll be a points system depending on how the stream was accessed.

Explains Billboard: “[The chart] will have multiple weighted tiers of streaming plays for the Hot 100, which take into account paid subscription streams (representing a full point value per play), ad-supported streams (representing a 2/3-point value per play) and programmed streams (representing a 1/2-point value per play). Those values are then applied to the chart’s formula alongside all-genre radio airplay and digital song sales data”.

On the main albums chart, the Hot 200, you have the additional challenge of equating track streams with album sales. In that countdown, Billboard says: “[This chart] will now include two tiers of on-demand audio streams. Tier 1: paid subscription audio streams (equating 1250 streams to 1 album unit) and Tier 2: ad-supported audio streams (equating 3750 streams to 1 album unit)”.
