Actually, if radio stations really want to, they can (and do) make their own swear-free versions of songs, even if the artist didn't supply one (although you'd think frickin' Columbia could pony up for an edited track to supply to radio, right?). I've seen a couple "clean" versions of Bright Eyes tracks there at KEXP. I don't know about the new one, though. But if enough people request it maybe they'll make a clean version; that's what production interns are for, right?
