Hi there,

Hi sviridpavlov,
Everyone needs to indicate this. Go to the “Settings” page accessed from your profile page. There is a “Performing Rights Organizations” button on the left side of the Settings page. If you are affiliated with a P.R.O. and wish to acknowledge that, then click YES and indicate the P.R.O. If you wish to not be affiliated with a P.R.O. for your AJ music, then click NO and that is all you need to do. Either way, you must do this in order to be able to upload your tracks.
