I dont really know what to give regarding feedback on music really, I guess his way of sharing the video should be different though.
Can you tell him that it's a good idea to share his social networks in description, give the video a unique title and etcetera.
Also he can design a 'standard upload' which is a template that enables each time he drags a video to upload. That way he won't have to write the whole description every time, video tags etc.
He can also check this site for well common special letters such as arrows or whatever may fit.
