I also think they have a relatively normal downturn, just their seemingly need to still be not just popular (they are) but culturally relevant (they aren't) is a key turnoff. But they still can write good stuff. Theirs an albums worth of good material since 2000, but spread out over 4 albums.

Guess what I'm yammer on about is most bands after 20 aren't releasing great work anymore. An obvious thing. Like I said. Yammering.
