Song analytics: the top ten tracks with plays, the 0 to 100 score and track affinity, for any artist

Song analytics in Opah reads each of an artist’s top ten Spotify tracks every 24 hours: lifetime plays, the track’s own 0 to 100 popularity score, and track affinity, the track’s share of current popularity divided by its share of lifetime plays. Above 1 a track pulls more demand than its size says; below 1 it coasts. For any artist you add, yours included.

$0.99 a month for your first 3 months on Opah Core, then $19. Cancel any time. Chartmetric is $60 a month for 10 artists; Opah is $19 for 3 or $39 for 10.

Track affinity, the riser

17.25×

Its lifetime plays: 7.3M
The flagship, at 744M plays: 0.17×

One artist’s top ten tracks, anonymised. Affinity is the track’s share of the catalogue’s current popularity divided by its share of lifetime plays: above 1, the track pulls more demand today than its size says; below 1, it coasts.

Measured 3 September 2026, artists anonymised.

Which track is pulling, and which is coasting

Plays say how big a track is. The score says how much it is played now. Put the two together across the top ten and every track gets a ratio: this artist’s 744M-play flagship reads 0.17, a hit coasting on its history, while a 7.3M-play track reads 17.25, pulling far more demand than its size would predict. That is the track to put an ad behind.

Both inputs are Spotify’s real numbers and the ratio is defined on the page, never a made-up unit. Spotify for Artists shows plays and the score separately and never the contrast.

What Opah reads per track

Every 24 hours, for the top ten tracks of every artist you add.

Lifetime plays: Spotify's play count for the track, kept daily so the gain between reads is the plays it earned; Every 24 hours
Track score: Spotify's 0 to 100 popularity for the track, as Spotify reports it; Every 24 hours
Track affinity: Popularity share divided by play share across the top ten; a defined ratio; Computed
Plays per listener: Top-ten plays divided by monthly listeners, the depth of the catalogue; in the Playbook, per artist across the niche; Computed
Release: The album or single the track belongs to, with its release date and label; Every 24 hours
In the ads: A Spotify track or album link appearing in the artist's Meta ads reads as a campaign in flight; Every 72 hours

What a good number looks like

“The popularity is calculated by algorithm and is based, in the most part, on the total number of plays the track has had and how recent those plays are.”
Spotify developer documentation, Get Track (opens in a new tab)

So a track’s score rewards plays this week over plays last year, and a track with a high score and a small play count is the one the audience is choosing now. Affinity makes that comparable across a catalogue: 1 means a track’s current demand is in step with its size; the further above 1, the more it is under-exposed. The Playbook reads the same per artist, as plays per listener, so a deep catalogue and a one-hit catalogue sit apart.

How to read these numbers

The score lags: Spotify's own words: "the popularity value may lag actual popularity by a few days: the value is not updated in real time."
Affinity is relative: A ratio across one artist's top ten says which of their tracks is pulling. It does not compare a track to another artist's.

The other things Opah does

Every plan includes all of them. Each has its own page.

The other half: the ad that pushed the track

A track that starts pulling usually has a reason, and the ad gallery on the same page often has it: the ad whose link goes to that track, dated. Read the affinity spread beside the campaign timeline and the push is visible.
