Imo, Dance of Death had some really good cuts (title track, Paschendale, Wildest Dreams), some good ones (Montsegur, Rainmaker, Journeyman), and a bunch of mediocre ones (everything else). A step back from Brave New World, but a slight one, and the two newer albums are still way, way better than anything Maiden did since Seventh Son.
I consider Paschendale to be one of Maiden's absolute best songs, not to mention one of the first where they used the triple guitar attack to its full potential.
