People playing music off their phones. So chavvy, so disrespectful, so pitiful. Imagine everyone did it. Also, these people usually have a comically 'hard' persona, but they're playing some Will.I.Am / Chipmunk ditty that sounds like a set of musical Christmas tree lights. Kids. Whenever people play music off their phones on busses, you should sing a long and dance in a camp way - they'll soon pack it in, or else risk being indirectly affiflillliated with an intelligent person.
