I can see that, but meh, it's a cover. The 'God Of Thunder' cover could be viewed the same way, too. Chuck Shuldiner was still an amazing musician though, and you could see the maturation process of each Death album from 'Scream Bloody Gore' to 'Sound Of Perseverance'. Leprosy is still may favorite Death release, even though I listen to Human a lot as well. Why? I'm not sure, I think it's just because it's a good slab of raw old school death metal that stays consistent the whole way through with no weak spots, and the guitar work is great as well.
When it comes to death and black metal, my knowledge is somewhat limited because they are not my favorite genres, like traditional and thrash for me. Although Bathory's S/T debut, Possessed's Seven Churches and Celtic Frost's Morbid Tales find themselves in my player quite often.
