This is another case of the old media beating a dead horse. The chicks are history. Any other celebrity dropping so far, so fast, is ignored by the media.
But the chicks criticized Bush, the US, and the ignorant fans who didn't get it (whatever "it" happens to be at the moment). That makes them old media stars, no matter what they do, say, or sing. They could release a collection of Yoko Ono orignals and the media would find them "brave," "original," and "daring."
