How do I receive music from third part Mewo users?

To do so, this third part Mewo user needs to add you as an Agent. 

Once this is done, you will receive an e-mail alerting you that this user wants to add you as an agent of his. 

In order to approve or reject his request, you just go to your "My Providers" page and click on the ✔️ or 🗑️ button.
