I have to admit after American Idiot, I wasn't sure what direction they would take but I've listened to some of the songs and the general consensus is that it'll grow on me. It's gotten pretty decent reviews all around.

21st Century Breakdown is currently one of the top ten albums in the US and the single Know your Enemy Invalid Video Link has done well.

Anyone listen to the album? Thoughts? Concerns? Any growth or Progression from Greenday?
