I'll take Johnny Cash's version of Hurt any day of the week - one of the most haunting songs ever recorded.
And how in the HELL can you have a top 50 cover list that does not include Zep's version of When the Levee Breaks - IMO their finest song, and probably the most subsequently ripped-off drum riff in history.
Who compiled this list, anyway?
I thought they wrote that themselves. Who did it originally?
