I have sympathy with both points of view. GT isn’t the site it once was, but it does still have some really good lessons.

Two years ago I would have recommended it to anyone. Today I’d recommended it to beginners and improvers, wishing to improve/learn technique and theory. 
Anyone just wanting a reliable source of great lessons on classic rock songs of the 60’s and 70’s might have to look elsewhere……

I sincerely doubt that the lost 300+ classics will miraculously reappear any time soon. Disappointing I know, but I suspect GT has decided, not withstanding the licensing difficulties, that it can’t rely on greedy music publishers to offer reasonable terms and old guys like me are not their market going forward. The lack of response from GT to users posts is just a reflection of the difficulty in communicating a revised business model which is guaranteed to piss off a sizeable percentage of their customers. Maintaining radio silence instead? Not sure that’s working either……..

That said, the current diet of obscure Stones tracks, republication of excellent songs previously published on GT and music all ready in the public realm seems a bizarre/desperate strategy!

So I’ll enjoy it for what it is and seek alternatives for all the lost song lessons.
