who thought this album would be a good idea
No, 3 songs were posted yesterday. You can find the other one that was released on their channel. I don't think we need an article for every song released on this.
"What is the album exactly?"
Sumerian Records bands covering Florence + The Machine's second album plus "Dog Days Are Over"
Wholly disappointing. Especially with the amount of potential that could of been had. The Darkest Hour rendition is one of the better ones (if not the best) while everything just sounds like garbage.
The omission of D.E.P. and Crosses really was the final nail in the coffin.

Digging: Nine Inch Nails - Add Violence
What is this even...
Who came up with this idea?
Never thought I'd see a concept for a cover album so abstract that bears nothing interesting about the concept.
