Becomes popular? It's not as if Green Day has been teetering on the cusp of mainstream acceptance for ten years. I don't so much mind the older stuff, but their entire manufactured image, i.e. co-opting emo fashion and Bush-bashing, makes me pull my hair out in frustration. So fake and ridiculous. Also, their music has never been good, but at least they used to know that.
That said, I kinda liked 'em in 3rd grade, so I voted for Fall Out Boy.
