A few weeks ago there was a post asking for suggestions for female fronted heavy music and I was really grateful to OP for starting the conversation and everyone in the comments for coming up with really great suggestions.
I’m wondering if we could have a similar discussion to share more mellow covers of heavier songs. Usually when I’m working I prefer listening to less intense songs and a chill cover of a heavy song I like is somehow very interesting to me.
The song that got me wanting more of this niche was a cover of Toxicity which I’ve had on repeat this week. I can also think of this cover of Seven Nation Army which is kind of similar as an example but I don’t really know a lot more like this.
Does anyone have any similar recommendations they enjoy?
Edit: All great suggestions so far, still working my way through them! I remembered another song which is this cover of Firestarter by The Prodigy
There’s a singer who goes by the name of
who specializes in doing “lounge-ified” versions of heavier songs. He’s probably best known for the cover of 
he did for the Dawn of the Dead remake from 2004, but he has several albums filled with similar covers.
The names come up as dead images for me.
The first link is to Wikipedia, the second is a YouTube video.
No idea why, but earlier the links looked like box outlines with a question mark in the middle.
For some reason the links don’t load for me but based on an earlier comment I guessed this must be Richard Cheese’s cover of Down With The Sickness? It’s a good one if so!
