I dont know if it has been done before, but fuck it, do it again
What are your favorite, or most well done, cover songs you've heard?
Mine:

In flames-world of promises
Norther-whichever offspring song it was
Estuary of calamity-a mansion in darkness
Cradle of filth-hallowed be thy name, sleeples... (most of their covers)
Graveworm-fear of the dark
Dimmu borgir-metal heart
COB-aces high


naming the band who wrote it isnt necessary, but go ahead if you like.
