I contacted TuneCore to resolve the issue with them Content I.D. matching videos using my music and it seems we've settled the issue. I haven't gotten a hard concrete answer as to when this issue was or will be resolved, but the TuneCore staff reassured me that they will comply with my request to remove my music from the YouTube content I.D. management system.
Thank you for your patience. If you are still experiencing content I.D. matches using my music through TuneCore, please bring it to me and allow me to bring it to them to resolve the issue.
