Sorry to break it to ya guys, but lots of albums in a variety of genres came out in both 2009 and 2010 than just whatever Pitchfork decides to endorse in the Indie-pop, folk, hip-hop and the occasional metal album categories. It's silly to say one year is weaker than another when you don't know half of what was released in any given annual.
On a more positive note, I don't think there's been a bad year for classical, ambient, jazz nor prog. since the turn of the century.
