Songs they should have never remixed/covered

Just finished (well sort of) listening to Simon and Garfunkel's "Sound of Silence" covered by Disturbed.

Now I am extremely disturbed after listening to it. I can understand poetic license, my MY GOD, that was freaking awful.

The best part of the song was at the end, when the silence started.

Do not even want to think what Disturbed would do to "Bridge over troubled waters"
