Tough one to call...I know which I prefer, but it's really close and I'd never bash anyone for liking Nazareth's cover of Emmylou and Gram's original.

Taxman Stevie Ray Vaughan > Taxman Beatles

I like Henley's better, but this is pretty damn good. <iframe width="420" height="315" src="https://www.youtube.com/embed/l4mN9cfmbnY" frameborder="0" allowfullscreen></iframe>

The Everly Brothers were the first to release the song in 1960.

Oh, and a point blank statement -- ANY cover of ANY Bob Dylan song sung by ANYONE ELSE, with the single exception of The Times They Are A'Changing. I hate Bob Dylan's voice. Hate, Hate, HATE. Somehow, I think it works great for that one song, but otherwise, take that nasally crap and go away.

Best cover of a Dylan song -- All Along the Watchtower, by Hendrix.

I like all flavors of music for the most part and can appreciate a good artist without hiding behind pseudo machismo.

Let's not get carried away now.

Freaking great cover:

I can't say i like this "better" than the original, but i do like this guy's voice. This is Cher's son btw.
