Still, you do need to judge a song for ALL of it's components. John's forte was lyric writing, and so he did tend to judge music with the words always as a first priority. For some artists, the words are a liability but the music is so great that the overall song is still very good. ACDC is a band that I would put in this catagory. And their lyrics do have their moments.
Music IS crucial to a lyric.
I think we get the better end of that deal.
