Hey Dan here is how you fix the copyright claim as I have used the song before. For the copyright claim it's as simple as putting the track in your description and putting. 'This track is licensed to the public under Creative Commons Attribution 4.0 International' Then linking the Cloister of Redemption song then appeal it saying you have a license. Add both the disclaimer and link to the song in your description before appealing. I used the song before and that is how I fixed the issue hope that helps. ❤
