YouTube created an automated content tracking system called Content ID (CID). CID scans videos and alerts copyright owners, such as musicians, when their music is used in videos on the YouTube Platform.
If the owner of the music has registered with Content ID, you may receive a Claim. DO NOT WORRY! If you have the license, then you have legal permission to use the music in your videos.
You can decide if you wish to disregard the Claim or dispute the Claim. If you are monetizing your videos on YouTube, then you will want to dispute the Claim. See "How Do I Dispute a YouTube Claim".
