I think it's pretty obvious that the list was not actually made by a real guitar player. Kurt Cobain should never be on any of these lists, love him or hate him he wasn't much of a guitar player and I would dare to say that his guitar playing also wasn't influential. His songwriting maybe, but not his guitar playing. No Chet Atkins or Tommy Emmanuel and then Angus Young barely making the list or some of the things that stand out to me. No Chet Atkins, seriously?
The thing I hate about these lists is that they don't even try to be objective.
