Interesting reconsideration. There are at least 3 albums that came out in 2006 that I never heard until 2007 that would have certainly made my top 10 for that year -- including what I now find to be 2006's best album, Waiting for the Next End of the World by Channels. The same thing happened the prior year, when I didn't hear Leviathan (Mastodon) or Funeral (Arcade Fire) until well after the year ended, and they're hands down the best 2 albums that year.
So who knows what else I'll find out about later that would overturn my list for 2007.
So well informed I don't know where the truth begins.
