First of all we must distiguish between:
-Spotify / Apple Music user profiles
-Spotify / Apple Music artist profiles
User profiles are not about music distribution. They are your personal user profiles which you used to listen to music. You can't use a user profile for music distribution.
Artist profiles are used for music distribution and it's where your music will be available for the "users" to stream. If you don't have an artist profile for Spotify or Apple Music select "create a new profile". If you already have music on Spotify or Apple Music and already have an artist profile then use that link and enter it in the Artist creation process of our website.
