Twenty-Eight Days, Rolling, Recalculated Continuously
The figure on your artist profile is a window, not a bank. Every day, listeners whose only play was 29 days ago drop out of it. An artist whose track had a good week in March does not carry that number into April.
This is why artists watch the figure fall during quiet periods and assume something has gone wrong. Nothing has — the window simply moved past the activity that was holding the number up.
For buying, the consequence is direct and unusual: this is a purchase with a shelf life. Bought listeners hold the number up for roughly four weeks and then start rolling off. That is not a flaw in the service, it is how the metric is defined, and any provider implying you can buy a permanent monthly-listener figure is describing something Spotify does not offer.
- Window:28 days, rolling. Not a calendar month, not a total.
- Counts:Unique accounts that played your music, once each regardless of how often.
- Decays:Listeners roll out as the window moves. Every artist's number falls when activity stops.
