When a video is uploaded to YouTube that contains licensed, digitally fingerprinted music, a "matched third party content"
copyright notice will appear alongside the uploaded video in the YouTube Video Manager (this typically appears shortly after uploading).
A copyright notice does not
mean that copyrights have been infringed, and this shouldn't be confused with a YouTube "copyright strike
". It's simply a notice to advise that YouTube has detected Content ID registered content within the video, and that further information/action is needed.
Again, if you've licensed the music from AudioJungle, you will be easily able to clear this notice and you shouldn't have anything to worry about.
