What contributes to Shazam charts? 

The daily number of Shazams contribute to the daily charts (not lifetime number of Shazams). These charts can also be viewed at https://www.shazam.com/charts/top-200/.  On an artist page Shazam count is cumulative, but you can also see the daily Shazam counts on the track page in Chartmetric.

Why does the #1 charting Shazam song have less overall Shazams than others?

The Shazam chart position is based on the number of Shazam’s in a 24 hour period. Example: the new song from Ed Sheeran has had more Shazam's in the past 24 hours than any other song, it will be number one.

How far back does the "Historical position" data go?

We have updated this data daily since Feb 22, 2019; previously it was updated weekly.

How do you compute the velocity of a track in Shazam charts?

This is growth in the past 7 days based on Shazam counts. ‘Growth’ meaning how many steps the track jumped up (or climbed down) on the chart.

Why do some higher performing  tracks have zero "velocity”?

If the song has remained in the same position for more than 7 days (e.g. charted at #1 for one week) then the velocity is zero as the song hasn’t climbed any higher… it has remained at the current position.

Some tracks have ’null’ velocity. This happens when the track is new which means we have less than 7 days to calculate the velocity. 

Additionally if a track has been out of the chart for more than 7 days, the velocity is reset. If it starts climbing the chart again the velocity will increase.
