Chartmetric tracks Shazam charts and displays chart history on Artist pages. Shazam was acquired by Apple in late 2018, so Shazam data has now been incorporated into Apple Music for Artists.

To understand how Shazam now works for Artists, please see this link: https://artists.apple.com/support/1109-shazam-in-apple-music-for-artists

To add your own music and make it discoverable via Shazam, please see this link: https://support.apple.com/guide/shazam-iphone/adding-your-own-music-to-shazam-dev9313a6a31/ios
​
Once you have a Shazam artist page you can add the URL by going to an Artist page in Chartmetric, selecting the Artist Overview section, and clicking the "Update Links" button under the Artist Data Sources.

Please allow up to 24 hours for Shazam data to start displaying on your artist page.
