Here is some information explaining how we collate our charts, as you will see from the images below, we have access via all platforms to individual artists/songs, this is the same data that contributes to the Official charts in each and every country.
We can access Facebook activity, Songs mentioned, songs played shared, song analytics, all counts of streams (Spotify, Apple, Amazon etc), sales (Itunes), shazam and radio airplay from registered music stations. Youtube numbers and trends are available to us to.
We then break down these charts to Individual countries, this lets us know what is hot in say Canada and what Canadians are buying, we hope this helps.
Any questions please message us via Twitter or contact Site owner firstname.lastname@example.org
No artists sales data is shared, and we will never do that, the exception is if an artist has charted in the Mainstream and would like stats and trends, but that would only be via consent from record labels.
