I posted in a thread of this sort a while back. And was deemed inhuman for preferring Tool's cover of "Imagine" to the original Lenon. It sounds depressing and creepy and I love it

I have a massive collection of Paint it Black covers. The one by GOB for the Stir of Echoes soundtrack was really good. And there's one done by the London Symphony Orchestra I believe which is an -amazing- orchestral rendition
