Chartmetric has more than 1.9 million artist profiles, and it's a lot to update all of them every day. To save bandwidth, we have different update cycles for the artists, based on their Spotify follower counts.
- Those artists having more than 10,000 followers on Spotify, we track daily.
- Those artists with 500 to 10,000 followers, we update stats every other day.
- Those with less than 500 followers, we do not update their stats automatically. You can click 'REFRESH DATA' button at the top right corner of the artist page, to update.
Our source of data for artist follower and monthly listener count is open.spotify.com. As a result, the numbers may be slightly different from what you see from the Spotify app. According to our observation, they are mostly in sync though.
