If you have licensed a claimed song for use from Friendly Music, any other music licensing company or the artist/label/publisher directly, a YouTube Content ID claim does not impact your license in any way. Think of it like this: When you pay for gas for your car to drive down the freeway you don’t get to turn off the billboards on the side of the freeway. A licensed song and advertising on a free social video site are related but not directly connected in any way.
The license you secured is most-likely a “synchronization” license between you, or a company that you are afﬁliated with, and the owner of the music copyrights that you are using in your video. A YouTube Content ID claim does not call into question the validity of your synchronization license. Your use of YouTube’s free service to broadcast the video has no connection with your license relationship whatsoever. The claim of a video by the YouTube Content ID system is simply for the purpose of identifying content in order to generate revenue by placing advertising near, around, before or after the video in order for YouTube to continue to provide the video sharing service for free to users.
