naccoachbob, there is much, much more to Justin's course than teaching you songs. You need to explore the site at justinguitar.com. He definitely teaches you how to fish. In fact, he makes a point of telling you to "suss" out the songs you want to play on your own, based on what he teaches.
Ear training, a major pain in the butt
, is a big part of his instruction.
I always recommend Justin because he's free, he's a good teacher, he's fun, and he's a good human.
