There's some analogy around learning to play a song without using your ears and painting without using your eyes. Like the silliness on the drawing side is obvious. The benefits gained by using your ears to learn music (again this is such a silly statement when you think about it) are so huge and so overlooked by so many beginner guitar players. An hour of learning by ear is worth a week of reading. Also, as I see it, youtube is full of perpetual teachers looking for perpetual students; being a perpetual student sucks. All you need is records.
