YouTube Copyright Claims
YouTube use algorithms that scans audio of the video you upload to check if you are using copyrighted material.
BjoKib´s tracks are not registered in YouTube content ID so you should NOT get a copyright notice using the music here. However this may change in 2022.
If you get a copyright claim and have a valid license. Submit your invoice / reciept on your youtubes “contest claim” page and the issue should clear shortly. If not, contact me and I will help out on my end.
