Inside the Signal
In listeners we trust. Not what they remember. What they do.
What Is Tune-Out Data
People tune in for a hundred reasons unrelated to the song on air: the hour, the day, a link shared elsewhere. When they tune out, the content on air becomes part of the explanation.
Most tune-outs are normal audience movement. The signal is in what remains.
One tune-out tells us little. When tune-outs keep clustering around the same song across repeated plays, the pattern begins to stand apart from the station's normal background movement. That repeatable pattern is observed behavior, not recalled opinion.
Removing the Background
Each play is measured against the station's own background at that moment: typical movement for that hour and weekday, surrounding songs, and one-off events like outages or major game nights.
The corrected result has a direction: a song can hold listeners better or worse than expected.
POP Score isn't a count of listeners who tuned out during a song. It isolates the smaller, repeatable part of that movement that remains after normal background movement is removed.
From Signal to Score
The result is a 0-100 POP Score, updated after every play.
POP Scores are specific to each station, reflecting how its own listeners respond to the music.
Each song becomes an ongoing music study as it airs across different dayparts and audience conditions. The correction makes those plays comparable. Without it, the same number could mean one thing at 7am and another at 9pm.

Most songs live in the crowded middle of the scale: only 10% ever break out.
The middle is busy with constant, small movements, like on a Top 40 chart. Songs trade places without much meaning. The top and bottom tell the real story.
Using the Score
POP Score is not a popularity index. As plays accumulate, it ranks songs by how reliably they hold listeners during real broadcasts.
NEW ADDSSongs newly added to rotation begin with Early Scores. As more plays accumulate, POP Score takes shape and generally moves less.1
Songs that hold listeners well can take longer to confirm than clear flops. A clear flop may show up on the first play.4
Early top scores are often a good indication of how a song will perform over subsequent plays.5
The top and bottom bands provide the clearest early signals.
New songs start with dimmed scores but may already show a top- or bottom-band badge.
Two situations where scores need time to settle:
- When a station first starts using Airplay Live
- When new songs are added to rotation
How quickly a score finds its level varies by station and depends on how a song differs from the station's overall sound. In musically consistent formats, differences in listener response can take longer to show.
The fastest song groups can settle in as few as 2-5 plays.6
For everyday scheduling, Airplay Live provides continuously updated music research for rotation and catalog decisions. Main View lets programmers rank songs by their current POP Scores, while Track View shows how individual songs perform over time.
One of the most useful signals: a song in heavy rotation starting to lose listeners.
Early-play measurement data
Airplay Live database
POP is the score. Everything else is the math behind it.
1 Play-to-play score movement fell by 46-64% from plays 2-10 to plays 21-28, tracking the same songs. Sample: 2058 songs, 57,600 plays over an average 9.4-month active-station window.
2 On The Big 80s, across 28+ consecutive scored plays, average score movement falls to about half its initial level by play 10.
3 Songs were matched at play 5 by score, timing, and rotation pace, then followed through plays 21-40. Half the catalog was held out to test whether the result held.
4 Songs that later ranked low already measured worse on average from play 1 on The Big 80s and play 4 on Dance UK.
5 On Dance UK and The Big 80s, 66% and 73% of songs ranked in the top 5% after five plays were still in the top 20% ten plays later.
6 Genres tracked by average score: on The Big 80s, New Wave and Rock settled within 2 plays and Pop by play 5; on Dance UK, Techno settled within 2 plays.
After the Score Settles
Settling doesn't mean a score stops changing. It means the initial movement has slowed down. Listener preferences can still change over time.
Dance UK example: score changes from play 12, measured 7-90 days later. Bands show the middle 50% and 80% of songs still receiving airplay at each interval.
Only songs still receiving airplay appear in later results. That's survival bias, live on radio.
Stations can request pilot access from Airplay Live. Setup requires a reliable concurrent listener count and a now-playing feed. No station-side installation, listener panel, or encoding is required. contact@airplaylive.com
