We work closely with Google Play. If you want to be a little more hands-on with the platform we recommend you use their Artist Hub. You can claim your page there and add a biography and image, though this does incur a small charge.
Sometimes releases by artists with similar names can get mixed up on digital services. We do what we can to avoid this with digital services that have artist IDs. If the issue arises at Google Play they prefer you contact them; you can do so here. Note that Google Play is included as part of the YouTube Red package. This means that those who are subscribed to YouTube Red will also have access to your catalogue through Google Play.
