There is no such thing as non-copyright music.
You should ask permission from author before using it, or you just contact Youtube but I don't think they will reply your complaint but just try it
You should tell the author that you using his music so he could fix the problem maybe
Maybe Youtube didn't know that it was non-copyright and it's free to use. That's why, OR you shouldn't edit the music.But the author has said anyone can use it without permisson.
