I would Kill to see

I don't think Opeth should cover a Pink Floyd song.
Pink Floyd is one of my favorite bands, and I don't think any band has any business covering them.

Korn covered a Pink Floyd song once... nasty.
If a contemporary band is to cover Floyd, surely you agree that they have the potential to do something good with the material. There are shitloads of awful Floyd covers, Opeth are one of the few contemporary bands that I wouldn't have a issue with them covering it.
 
I have been saying that Floyd should cover "Echoes" or Sheep or Dogs for awhile now.
Also, Epitaph by King Crimson. Now that would be perfection.:worship:
