Methodology

NGMC is a weekly chart for Nigerian gospel music with global signal scope. We track how Nigerian gospel songs move across trusted digital platforms, then rank them using a methodology built around recent momentum, verified song identity, and chart integrity. We do not simply rank the biggest lifetime songs. We aim to reflect which songs are genuinely moving now.

Our chart draws from YouTube, Audiomack, and publicly visible Spotify data as performance sources, while Apple Music plays an important role in identity and metadata verification. That means we care not only about numbers, but also about whether the song, artist, and platform source are being matched correctly.

NGMC does not host or store music audio for chart ranking. We store song identity, source links, platform metrics, metric history, eligibility decisions, and published weekly chart snapshots.

Spotify data is treated as a public play count signal where available. NGMC does not claim access to private Spotify royalty reports, label dashboards, distributor dashboards, or Spotify for Artists account data. We track visible count movement over time and use it as one part of a wider evidence set alongside YouTube and Audiomack.

Because public Spotify visibility can vary by track, artist, and availability, missing or inconsistent Spotify data does not automatically disqualify a song. Where Spotify data is unavailable, the song may still be assessed through other verified platform signals and metadata checks.

To rank, a song must first clear a minimum weighted performance threshold and show enough valid data maturity to be treated as an active chart competitor. Older songs may still qualify, but they face stricter entry conditions than newer songs.

Once a song is eligible, NGMC scores it primarily through current movement using recent velocity across today, 3 day, and 7 day windows. A smaller catalogue layer remains in the model so the chart can still recognise scale and sustained relevance, but movement leads the final outcome.

NGMC also includes protections against coasting, duplication, suspicious spikes, weak source matches, and artist overcrowding. Songs are not allowed to remain highly ranked just because they were big once. They must continue showing enough present force to hold their place.

Our charts are refreshed through the week and published on a weekly cycle. Public chart weeks are treated as stable published snapshots rather than casually rewriteable lists.

If a song appears in the wrong genre, has a missing contributor, has been matched to the wrong version, or appears to have incorrect platform data, it can be submitted for review. Corrections do not guarantee a chart change. Every review is checked against source data, metadata quality, chart rules, and the published chart cycle.
