Curating a playlist is more work than just putting songs in a playlist. It entails reviewing submissions and placing them, as well as doing your part to grow the playlist (ie sharing it on your feeds, encouraging artists you know to submit, posting in groups and hashtags that apply, etc.).
HERE'S HOW YOU GET PAID (anywhere from $20 - $200/mo depending on work done):
Once your playlist has been moved to the paid submission platform (because it's grown a certain percentage) from the free submission platform, AFRP will take a flat fee from each purchased placement campaign, the remainder will be given to the curators whose playlists a given song has been placed in.
