Death Magnetic. There are some pretty good tunes on Load. I don't despise the Load and Reload albums, especially the first one nearly as much as many others do. That said, Load is next up to go after DM in my mind.
If I would have to came up with the bottom of my Metallica albums ranking, it would be like this:
7. Load
8. St Anger
9. Reload
10. Death Magnetic
Indeed there are some good tunes on Load, Bleeding Me, The House Jack Built, King Nothing, Cure, The Outlaw Torn.. I like that album to be honest.
