A song murdered by someone.

Eric Burdon, Paint it Black.  Enjoy.

Just about anything from Rod Stewart’s “Great American Songbook” series.  

@frogman  --  RS should have been charged with a crime for sure. 

There should be a law against anyone covering Unchained Melody. In fact, even though the live version linked to above is pretty amazing, I'd say that the only version that should ever be played or sung is the original studio version. It's perfect. 

I hate to say a bad word about these two, but:

Aretha covered the Beatle's Eleanor Rigby. I have it. Its pretty bad.

I also don't like Otis Redding's cover of I Can't Get No Satisfaction.

I do like Wilson Pickett's cover of Hey Jude with Dwayne Allman on guitar. Its a different song altogether which sometimes makes a cover okay.

Guns and Roses' version of McCartney's Live and Let Die.
