Metallica doesn't give their song "- Human" (or "Minus Human") much love. The song was composed for the S&M live album and has only been performed four times ever, despite having some insanely beefy riffs. Guitarist and YouTuber Mega Beardo (and bassist for Byzantine) clearly got sick of Metallica not playing the song and not only decided to cover it, but make it even doomier than the original. The result is crushing.
And seriously Metallica, it's been 24 years since "- Human" has made the cut as a live song. It could very clearly be done without an orchestra, and it'd kick major ass. Just do it, will you?
