Why do teenagers play music on their phones, especially in public transport and not understand that it is annoying and irritating to others? Why do they feel that need to share, or rather to force others to listen to their music? It is called sodcasting and playing loud music is a way by which young people try to own the space. Teenagers are not anti-social, but just marking their territory. They create an environment suitable for them. Back in the eighties teenagers carried these massive boom boxes and before that young people listened to their tape recorders. Music is of all times and ages and young people do not do anything wrong, but listening to their own and each others music.
