Some people have taken it upon themselves to call it ''mind pollution''. This meaning anything heard can damage one's thoughts, way of perceiving situations and demoralising values. Certain musics have been accused of doing just so. For example, Eminem.
Eminem made a song titled ''Kim'', which is all about torturing and murdering his ex-wife for everything that she did to him. Let's face it, it may not have been the most appropriate song, but music reserves the right to express yourself freely. It's an art, and it encourages blossoming!
Some songs have even been banned from radio stations and anything public because of content, language and imagery. Do you really think that because a song says rob a bank, you're really going to go rob a bank? Hasn't your mother ever told you 'if your friend jumps off a bridge, does that mean you will too?'. My answer to that has always been: ''is there water at the bottom?''. What I mean by this is we all have the freedom to think and decided for ourselves what we will do. It's our own will to choose. If I want to jump, I will. If I don't want to rob a bank, I won't. It's a question of up-bringing.
So the next time someone says that a music that you enjoy is inappropriate, maybe ask them if it really is, or is it just a lack of appreciation they have for art.
