When logged into the SMS at https://www.symphonicms.com go to distribute > view releases > find the release and click on the release name > when viewing the details of the release, you will see a "Partner Links" tab.
Here we list the links of partners we can pull the release page data from.
This is helpful for promoting the release before the release date and for providing links to your fans once the release has come out.
Currently iTunes is the only partner we can pull this page data from. We display it as soon as we can fetch it for you. We are in the process of adding additional partners to this list.
