I am trying to add some songs to my list on YouTube, such as: https://www.youtube.com/watch?v=8-mMGu-Spm8 and the other Octopus's Dream videos.
However, when I see this video: https://www.youtube.com/watch?v=IE3JfAWRifk
I cannot add it to my list. How can I do it?
P.S. and I don't particular understand why this kid song may cause harm to my list. Can it damage me, or damage my audience? If my audience that views my list sees a kid's video, would it be so bad that it hurts them or somehow they don't have the capacity to view a kid's video?
