The thought that people think Madonna's cover > Don McLean's original, makes me want to kill myself.

I'd say Jimi Hendrix's cover of "All Along The Watchtower" (Bob Dylan) is better, though I love the original.

Also love Adele's cover of "Make You Feel My Love" more than Dylan's again... Placebo's cover of Kate Bush's "Running Up That Hill" is better, love both again.

Alanis Morissette's cover of Seal's "Crazy".
The Kooks' cover of Ace of Base's "All That She Wants"
Rufus Wainwright's cover of Leonard Cohen's "Hallelujah" (though his is better than Buckley's and Alexandra's)

and, and I know this will offend a lot of people, but I prefer the Scissor Sisters' version of Pink Floyd's "Comfortably Numb". They're both on my "fave songs ever" playlist though.

EDIT: Are you on drugs? Are you ****in' on drugs?
