I would say that it depends on the kind of music teens like to listen to. In my personal opinion, I think that rap and reggae music have a bad influence on teens because teens like to imitate the way their favorite singers dress or look like. Teens see some singers as their models, that is why, there are even some teens that imitate the way their idols talk or act. This happens because at this age, teens are not sure about their personality, and they adopt different ways to act. It is as if they were tryin g to find the appropriate personality for them!!!
