Their career isn't over.
They'll still get play on NPR... ;-)
Psuedo-Country on NPR! Do you think the elitists would ever stoop to such a level? That would be fun to watch!
Prediction: look for CRITICAL acclaim now. After Steve Earle wrote some sort of paean to John Walker Lindh, his name started popping up on "greatest artists of all time" lists. Prior to that he was just another loser junkie riding around in a bus 300 days a year.
That'll be the mainstream media's reaction. I expect Rolling Stone and all other music media critics to suddenly find Dixie Chicks to be on par with other leftie loser/heroes like John Lennon, etc.
The next Grammy awards are in about 11 months? Fearless prediction: the Dixie Chicks win 11 awards. (Ok, maybe just 7.)
