Sounds like sour grapes to me...I don't mind Green Day, I play "American Idiot" once in a while...one of my friends thinks Dookie is their best work we agree to disagree about that.
If nothing else it gets GD's name in the press, and as Sooty loves to say any publicity is good publicity.
Around American Idiot, they got a bit too political for me, I don't listen to that album or the new one because I don't really like the tunes as much as the older ones, but I can deal with artists being outspoken and political, but when they try to make their music fit the image, I lose interest... Green day started to make their music sound stereotypical to the image that it seems they were trying to present, IMO.. They also lost the sense of fun in their music... So, Warning and Dookie for me
