But there’s a solution for this kind of emails, trust me, there’s no need to appeal on YouTube. The distribution company may confirm the claim and you’ll end up getting a Copyright strike, not to talk about that, if you win the appeal, YouTube will only whitelist your own video and continue claiming any others.
It’s your own responsibiliy to keep your beats catalog as healthy as possible to be taken seriously by your customers.
