The answer depends entirely on the music stores but we have outlined top stores below. In many cases, especially for smaller stores, you may need to contact each store individually or perhaps read through their FAQ’s to see if they explain there.
For the more well known stores such as Apple Music/iTunes, Google Play, Spotify etc. here’s what we know:
Apple Music Connect
As the Artist, Band Member, Manager or Label rep, you can sign up for Apple Music Connect to manage your Apple Music page (or artists you manage):
Spotify for Artists
You can verify your artist profile where Spotify handles verified artist profiles directly. See https://artists.spotify.com/faq/verification for more info.
You can update your artist image and more on Spotify without a verified profile by signing up for the Artist section as well as accessing stats and other great info.
Google Play Artist Hub
Similar to Apple Music Connect, with Google Play you can sign up to the Artist Hub and claim access to your artist page to manage.
Shazam for Artists
You can manage your Shazam profile by signing up for Shazam for Artists.
If the above info changes or you have more info to add to the list, please add it to the comments and we’ll add it to the list!
