I did not know much about Cohen before I read the article about his death. I heard the Jeff Buckley song of course because it appears in Shrek. I also think that the Irish girl did a cover of Bird on a Wire that I like. He did a lot of work and was an influence over much of the music scene. It was sad he got ripped off and had to work so hard to re-earn his fortune. It is an informative article and worth a read if you don't know much about him.
