Song Grade 8 minute read
What the Spotify popularity score measures, and how to read it
What the number is
Every track on Spotify carries a popularity score between 0 and 100. It is not a stream count. It reflects how much a track has been played recently compared with everything else on the platform, with recent plays weighing more than old ones. A song that was huge three years ago can sit below a small release that is being played a lot this week.
Why it matters
The score is one of the few signals about a track that anyone can read, and it moves in step with how much the recommendation features are picking the song up. A rising score in the first weeks usually comes with more algorithmic plays; a flat one means the release is living on its existing audience.
Why a single reading misleads
A score of 30 on day four is a strong start. The same 30 on day forty is a release that has stalled. The number only means something next to the age of the track, and next to what is normal for you and for the genre: a 40 in a small niche can be a standout while a 40 in mainstream pop is ordinary.
How to use it
Record the score every day from release. Compare each release with your earlier ones at the same age, not with their current values. Decide in advance what you will do when a track is clearly ahead (keep the budget on it) or clearly behind (stop, and learn what was different). Song Grade automates the recording and the comparison.
