How do music charts turn streams and sales into a ranking?

Several inputs, one ranking

Many modern music charts combine streams, sales and sometimes radio or video activity into a single figure using a defined formula. Because streaming now dominates listening, the way streams are weighted strongly shapes the result, and the exact weighting is set by the chart.

Not every stream counts the same

Charts often treat paid subscription plays differently from free or ad-supported plays, and set rules on how many plays from one listener count in a period. These rules exist to limit distortion, and they mean raw play totals and chart points are not the same thing.

Reading a chart move honestly

A debut at a high position usually reflects a concentrated release-week push. A song that climbs over several weeks is often showing growing real interest. Neither position proves lasting popularity on its own, so the trend over time is more informative than one week.
