Leonard Cohen is probably the most prolific and important writer out of all that are listed. He has been relevant for so long and will always remain relevant. His writings, whether they be books, poetry, or song, are forever timeless. If you haven\'t educated yourself on this incredible mind and heart than you are truly doing yourself a disservice. Should you ever actully catch him in concert, he is now 74, you\'ll never forget the experience. He surrounds himself with excellence and it\'s really remarkable.
