A case in which you use the
materials for Youtube
I apologize for the inconvenience, but I would like you to always write the copyright when you use the music materials and the sound effects of MusicNoteWorld for distributing a video to Youtube.
If you use the materials without writing the source of a quote, not only the possibility of “matching a third party's content” is raised when other people use same materials, but there is a danger of being against Youtube's guide lines when you get the advertisement income.
There is the example that how to write the copyright.
