The current situation with the music creators and performers is a total over saturation.
From YouTube and soundcloud alone you can see that there is too much performances and new original content to even closely be unique or have a value of its own based on aesthetic value of the art itself.
Looking at the popular artists on youtube - its a matter of production value for the most part, Lindsey sterling - super professional videos and not so may compositions even at the beginning of her way.
Famous music teaching channels also have strong video creation skills plus charisma plus some promoting as they admit from time to time.
The last interesting category is the channels the went viral, those split into 2. The ones that don't create anything anymore and the ones that actually kick started the rest of the path.
