In my opinion, Disturbed's cover of Simon and Garfunkel's "Sound of Silence" replaces Smash Mouth's cover of "I'm a believer" and Pearl Jam's cover or "Last Kiss" as the worst cover ever. However, many people really like Disturbed's version.

What are your thoughts? Any favorite covers?

A few that I like:
Fugees - Killing me softly
GnR - Knocking on heavens door & Live and Let Die
Gary Jules - Mad World
UB40 - Red Red Wine


I hate almost any cover of Unchained Melody.
