Obviously I am not a Youtuber, but does he really need a face and 'talking to the audience' after each video? Why can't a channel just be pure content.

If his songs are good - I subscribe. If he makes 10:02 long videos chatting about his social media and swag, I unsubscribe.

Note to OP that these things actually probably do work, as everyone is doing it. I'm just ranting as I personally hate it.
