9. Jay-Z, The Blueprint (2001)
10. The National, Alligator (2005)

a preponderance of consensus/canonical in the first three to four years of the noughties ... and hardly anything from after 2005

i don't buy the "takes time for the dust to settle" argument, okay it might serve to slight 2009,maybe 2008 stuff in the tally.... but you could equally make the argument that more recently released stuff is fresher in the memory (after all, that seems to happen with end-of-year polls, stuff from early in the year fades a bit and suffers for it)
