The main problem with Cobain being on the list is that most of you all probably have atleast one casual guitar playing friend who is a better player than he was, or you may even play better yourself. Most of the kids I've taught over the years can play better than him, and we're just talking a couple years of lessons, nothing crazy here. It really makes no sense based on the title of the list. There are probably thousands of established guitarists who are better than a few of the people on this list.
