I think that Leonard Cohen's own version is the best as he sings it how he meant it to be sung.

I do, however, like Jeff Buckley's and kd lang's versions while a friend swears by Bob Jovi's.

There's a horrible version by Bono on 'Tower of Song' - a CD of Cohen covers.

The main thing is that Leonard will be getting lots of lovely royalties from the X-factor version - thanks, indeed, to Simon Cowell.
