Content ID will claim on any YouTube video that uses your audio
By selecting YouTube as a store when you create your release with Identity Music, you are submitting your music to content ID
This then claims on any video that uses your audio on YouTube
Content ID is a system built by YouTube that allows copyright holders (e.g. record labels, music distributors, publishers, etc.) to protect and monetize their content on YouTube. Through YouTube’s Content Management System, copyright holders are able to upload content that they own the rights to (e.g. audio files, films, etc.) and assert policies for the content. Once the content is uploaded, YouTube’s automated system fingerprints it and searches through all the videos hosted on YouTube. When it finds matches, it applies the policy provided by the copyright owner.
