So update, I have sent an email to youtube, breakingcopyright.com is already aware of this and is in contact with youtube as well. If you've gotten a strike or if you see this and think this is crap, I've been told to recommend going to support.google.com/youtube and using the chat option

Correction, it's a community guideline strike because YouTube thinks that royalty-free music is harmful or illegal? I should note that this is the same service as the YouTube Audio library and uses the same creative commons license.
