I am another one who gets extremely pissed off with morons playing their dumb ringtones on the bus. I have noticed on the buses in Stoke-on-Trent that there are notices saying that playing personal stereo equipment loudly "may contravene our Conditions of Carridge", and that offenders may be asked to leave the bus, like that will ever happen. I have no problem with headphones though unless that are mega loud, still less annoying than mobile phone speakers (which make me want to take a sledgehammer to the offending phone, or wish I was in possession of small, directional EMP pulse emitter), but still, can't be doing the person's ears much good...
