The ads I've seen feature songs (except for You Really Got Me by my beloved Kinks) I just don't even like much less want to play. I don't know how that works--do they have a choice of stuff to choose from? Because why I'm hear and messing with JamPlay and looking around for on-line instruction is I want to learn the music that inspired the rock I loved all my 58 year life. That's what my Brit heros did and now I get it so much more. I can play most rock stuff. I can't finger pich ragtime blues nor do I know all those cool bluegrass licks but playing that kind of stuff makes me happy and entertained. That rock stuff was light of a jay 25 years ago and go to town on my gear. Retro is where it's at for me. If that new technology addresses that too--and not just tab, I'd like to know and buy in. But I ain't paying to play no Aerosmitth or Van Halen.
