I can't help but notice the parallels between this argument and the ones that have been raised in America on the subject of 'Violent Video-games'tm.
The US media seems to have driven itself into a frenzy that computer games involving violence can actually instigate the users to carry out improbable and extreme acts, as if on the basis that children can be manipulated by something they see on a screen. This is the exact argument i've seen used for 50 cent's music, that the spoken word can incite violence in impressionable youngsters. However I believe it is not so much the lyrics portrayed within, but specific factions and bands in Rap and Hip Hop music have lot to answer for in the overall image they represent.
Whilst the escapism of sexy ladies and fast cars is easy to deal with, certain groups seem eager to press the more 'hardcore' aspects of street culture to gain their audience - such as drug use and gun crime. Now don't get me wrong, i'm not reverting to the age old 'get told something and you'll do it' argument, what I am saying is that constant references to such things, be it in the media or in music, are encouraging the acceptability of weapons and drugs on the street and in society. The gangsta rap posse for example, can often assert the role of guns as status symbols, as objects, and falsely represent the credibility that goes with the owner of such an item, sometimes describing it as the definition of manhood - and therefore another form of inviting peer pressure
This is where my real problem lies though, not the message behind rap but the almost retina searing collection of images and influences we're subjected to on a daily basis, for which the blame does not lie solely on music and the solution is not based the censorship and removal of anything that offends us. The true blame lies in our society, its structure and the current trends and fads. The current celebrity culture is mis-representing almost everything that should be important with what shouldn't be, too much stock is placed upon beauty and 'get rich quickness' and not enough upon what really makes the world tick. In such a world, it can be difficult to find your way - to carve your niche in a normal place when you're always being told fame is one step away. As a result, I find it easy to believe that individuals begin to become confused with what is really going on - taking what is essentially a rapper's fairly innocuous and exaggerated life-story told in music and taking it as gospel, following someone else and instead of creating their own identity and resorting to media accepted ways of gaining recognition and 'cool'.
If you look deep enough, anything carries a message, it's just that rap music's isn't too hard to find - it's the obvious thing to blame for screwing up our kids at this moment in time. I can't deny that Rap music can sometimes carry an aggressive message - but I do believe that the media should take responsibility for something that they are also repsonsible for maintaining and encouraging in equal measure.
