The 28-day window and what it means for planning

Updated 5 October 2026 · 2 min read

The window is the single mechanic that governs how your number behaves over a release cycle. Treating it as a calendar month produces a promotion plan that arrives late and leaves early.

How listeners age out

Every listener who played you is inside the count for 28 days from their play, then leaves it — unless they play you again, which resets their position. The total is therefore a moving sum of 28 overlapping daily cohorts.

When a release spikes, the spike leaves in the same shape it arrived, twenty-eight days later. That arithmetic produces the long slide artists interpret as failure.

Planning around it

Work backwards from your release date. Pitching should start four to six weeks before so coverage lands inside the window. Promotion should continue for four weeks after so the decay is offset by new listeners entering.

A release pushed once and abandoned is guaranteed to produce a spike and a slide, because nothing replaces the listeners who age out.

Using decay as a deadline

Treat day 28 as the point at which the release stops working for you. Anything you intend to pitch to — the second tier of curators, the regional press, the radio follow-up — should be scheduled before it arrives.

Frequently asked questions

Is the window 28 days or a month?

Twenty-eight rolling days. It does not reset on the first of the month.

Why does my number fall exactly four weeks after a playlist add?

Because those listeners were inside the window from the day they played you and they leave it as the window rolls forward.

Does a repeat play reset the clock?

Yes. A new play starts a new 28-day period for that listener.
