You have all the rights and there is no violation of copyrights. Nevertheless, social networks (YouTube and Facebook, for example) have automatic checks set up to file claims if content which is not from the public domain is detected.
To clear a claim via YouTube, you simply need to let YouTube know that you have licensed the music and have the rights to use it. Simply choose to “dispute” the claim by clicking the “matched third party content” copyright notice next to the video in your YouTube Video Manager, or on your dedicated YouTube copyright notices page. After you click “file a dispute”, select the option “I have a license or written permission from the proper rights holder to use this material”.
In the “Reason for dispute” box provide something like “a license to use this royalty-free music was acquired from Audioblocks.com (via Animatron.com)”
Usually, it should take a couple of days for the claim to be removed.
Please let me know when claim is removed or is still there after several days from now.
If for some reason it’s not resolved we will contact our audio provide (Audioblocks) and remove the claim through them. We did it several times already and all went smooth.
