Guitar really is discouraging, isn't it? I suppose all of us try to emulate the greats too often. Hell, I don't even know a single full song (aside from Rush's Tears, and even that I'm not sure I've mastererd). Every once in a while, I wonder if it was worth getting my Washburn. But then I sit down and go fucking crazy and realize... yes, I'd be a fucker not to think it was worth it.
So to all the guitarists: what was the first song you learned? Not necessarily full, but what was the first song you tried on your guitar? Mine's Tears (from 2112). That and the intro to Iced Earth's Dark Saga.
