Soca Charts Methodology


Soca Source Weekly Top 20 is the Soca Industry standard record chart for songs, published by The Soca Source.  Chart rankings are based on digital sales, radio play and online streaming around the world.

The tracking week for sales, streaming and airplay begins on Friday and ends on Thursday – a new chart is compiled and officially released to the public by The Soca Source on Tuesday.  Each chart is post-dated with the “week-ending” issue date.  Example:

    • Start: Friday, June 17
    • End: Thursday, June 23
    • Results Released: Tuesday, June 28 (“week ending: June 23”)

The methods and policies by which this data is obtained and compiled has changed throughout the charts history.  The chart was originally tracking Tuesday – Monday, but as of results dated June 28, 2022th, has been updated to align with Billboard standards.

The Soca Source “chart year” runs from the first week of December to the final week of November.  The altered calendar allows for The Soca Source to align with industry standards as well as to calculate year-end charts and release them in a timely manner.

Chart Methodology

Charts rankings are calculated by our proprietary algorithm which considers a variety of inputs including daily & weekly peak position (Apple Music, iTunes, Spotify, SoundCloud, Shazam & Deezer), geography and radio airplay. Other factors include the total weeks a song spent on the chart and its peak position.

Songs at the peak of their popularity at the time of the November/December chart-year cutoff many times end up ranked on the following year’s chart as well, as their cumulative points are split in the two chart-years, but often are ranked lower than they would have had peen occurred in a single year.
