I have all his albums. I would qualify that by adding, "...early Leonard Cohen is fantatsic." Have you actually listened to Dear Heather, his latest? A very worthless "effort" (or lack thereof), a real waste of time, a pity. At this point he's *completely* given up on trying to sing.
I like everything he did up until I'm Your Man. Cohen has a fetish for antiquated and primitive synthesizers which he collects, but which were justifiably discarded ages ago because they SUCKED. His more recent efforts all suffer from those plinkety-plink, rinky-dink, squeeking, honking, bleeping, tiss-boom-tiss-boom CHEEZY synthesizers. Set the controls of your cheap little Yamaha for "bossa-nova" and *boom*, he has a "song".
The "production values" (and I put that in quotes on purpose) of his recent work leaves a lot to be desired, IMHO. It really cheapens and wrecks his songs for me.
Personally, I would LOVE it, if he would record an all-acoustic album with REAL INSTRUMENTS. Just my own disgruntled opinion, FWIW.
If anyone wants specific recommendations on what versions of what albums to buy, I have them...
