Why do teenagers play music on their mobile phone loudspeaker on public transport?
they are challenging people to say something, and they feel they are powerful and superior because no one says anything, these teens are usually the ones carrying knives or who wouldnt think twice about causing someone serious injury, again things that make them feel superior, the underlying truth is they are insecure and lonely. Then again there are some airheads who are simply completely oblivious of those around them and are probably on the wrong bus or train anyway. the poor choice of music is just whats popular with people nowadays, re-released old song with slightly heavier bass and some rich african american raping over the top.
