Obscene language or dirty words in modern music
I think one of the most terrible things that teenagers have to listen to is dirty words or obscene language in modern music because it makes them more violent and more permissive to violence.
Teenagers are exposed to different things in modern life. Explicit obscene language is one of the most outrageous because it implies insults and references to sex in a way in which love is not present but reference to sex is used to talk about selfish satisfaction and pleasure thus destroying purity and self-confidence in teenagers.
When teenagers are taught these horrible language then they act like sheep and start cursing and they tend to think that women or men are just objects to satisfy their desires.
One thing parents can do is showing adolescents the riches of classical music or romantic music or free of bad words music that instead of filling their souls with violence give them hope and love for others. Nice music has a multiplying effect: it creates nicer people.
