i think more people would like rap if they heard guys like mf doom. just like neko case demonstrates that country lyrics can be lyrical and coheed and cambria practically scream through their guitars that rock can have substance, doom and his ilk stand alone trying to save rap. no one who really appreciates rap can even think of jibbs or 50 cent or li'l wayne as belonging to the same genre; it's akin to lumping led zeppelin in with nickelback. to sum up, i'll quote doom himself from his song "Old School" (with Talib Kweli) : "And since when lyrical skills had to do with killin a cat? What type of chitlins is that?"
