I'm with most of the folks here. Learing both songs and lessons are important. What I habve been trying to do lately is to learn songs that aspecifically employ techniques I'm studyin in the lessons. So if I'm studying root/chrd strumming, for onstange, I learn a few songs that use root/5 strumming. Or I take a song I already know and apply the technique to it.

I see now in the Fundamentals courses they have some recommended songs to go with the various chapters. I hope they do the same for the pother courses.
