Undeniable that much of what is posted on YouTube is substandard.
However there really are some great contributions.  I draw your
attention to those uploaded by our MMDer Bob Taylor.  In particular,
have a look and listen to his Duo-Art reproducing pipe organ at

Then search on YouTube for "ampicoab" to see Bob's other very good
contributions, along with a neat visual surprise.

YouTube is not all bad.  There are many excellent videos up there.
Don't be discouraged by the bad ones.
