One day when I was about 15, I found a record album called Songs of Love and Hate in our local pharmacy's discount bin. In solidarity with the advancement of Canadian culture [yes, that's how I thought in those days but gimme a break, it was the early 70s], I bought it. My first thought after listening to it was "Geez, this Leonard Cohen guy can't sing worth a shit!" But his song lyrics were very intriguing and I just had to keep listening. Then I started reading his poetry and novels. And I grew to love his music, especially once he got a jazzier sound with more complex instrumentation and percussion, along with fabulous female backup singers to offset his still rather monotonous bass-baritone voice.
As he aged and matured (or perhaps as I aged and matured), I found his music got more spiritual, more political and more humorous. The man's a genius, what can I say? It's beyond me how anyone can think that Leonard Cohen can't sing or that his music is depressing. They're just not listening.
