Your vote for greatest (covers) album

A full on cover album is hard to come by. Early Stones and Zeppelin covered (or "borrowed") extensively.

Jeff Buckley has the single greatest cover of Leonard Cohen’s Hallelujah.

Current favorite/fun covers are from Lake Street Dive.

A better question is who’s cover’s are better than the original. As in see above...

+1 Motörhead: undercover. Great songs with great production by a great band. 

Thanks Mickeyb!

Thought I was a lone voice in the wilderness with my Motörhead Undercover suggestion.

It really is well done all round and Lemmy manages to pull It off very well.

My vote for album of covers is Ummagumma by Pink Floyd. The album cover is actually a cover of the painting inside the cover photo. The painting, which is a cover of the painting within the previous painting, which is a cover of the painting in the preceding painting, which is a cover of the painting in the previous painting.

(Just in case the subject changes back and forth again).
