Jim Lerman's insight:
This seems to be about the simplest way to download (or extract) the audio from any online video, YouTube or otherwise. The tutorial was created by a 12 or 13 year old young man. The video part is right on, some of the audio is a little hard to fully understand. All in all however, after I viewed half a dozen different tutorials on this topic, this was the easiest and least complicated way to do it.
