Smells Like Teen Spirit is one of the songs (like some that are not outdated, e.g. Shout by Tears for Fears and Unbelievable bij EMF) of which the production is so fresh and new that you are in a different world. Heard it when it was released, so am not influenced by the tragic events afterwards which made Kurt Cobain a sad legend. Listening to it again, Nevermind is still as brilliant as it was, my favourite oddly enough Polly. Expect at least 4 average, else much music is wasted on some folks
