Kurt Cobain was already very famous. He was at the height of his career and if he would not of committed suicide he would of still came out with very good material. He wasn't a good guitarist but he didn't care. What carried through Nirvana’s songs was great melody and he wrote very good hooks and used the guitar to convey his words. What he also had was a very good singing rock voice. Anyone can learn to play the guitar all they want but either you got a good voice or you don’t. He should be respected as a good artist in his own way as well as any other musician, famous or not.
