User generated content [UGC] is used to describe any content created and posted by a user on online platforms such as social media platforms like Instagram or YouTube.
If you have opted in to have your music delivered to the social media platforms available, this will enable users to use your music within their own created content. For example, an Instagram user may upload a story and choose to include your music in their created video.
