Sociologists would also recognise that music and music culture plays an important part in creating cohesive identities for many people. Music and culture generally is part of the way society speaks to itself and understands itself. You have chosen to look at what might be called western popular music and culture, leaving aside vast areas of music that exist apart from this. While it is true that some of these music genres you mention have cultures in which some people sometimes act in negative ways, there are many many more for whom music plays a vital part in the way they think about themselves and express their views and who live decent and ethical lives. Music has been a force for political and social change and for spiritual uplift and joyfulness. Young disaffected blacks have found a voice and a cultural identity in hip-hop, the working class youth of Thatcherite Britain found a perfect way to challenge the soulless culture of the time through punk and that also led to a strong anti racist platform in Rock Against Racism and various anti-fascist discourses that took place and this is just the tip of the iceberg. Music has brought great happiness and meaning into the lives of people since civilisation began and to dismiss it all with the wave of a dogmatically religious hand is simply foolish. There is not even a clear foundation for it in Islam and there is a wonderfully rich musical tradition within Muslim culture and I'm not talking about Yusuf Islam and Sami Yusuf et al. Morocco, Egypt, Saudi Arabia, Turkey, Iran, Pakistan, Afghanistan - you name it and there has been music being made by Muslims for centuries, music that does not encourage the negative trends that you seem so worried about. The medium is not the message and to dismiss music in its entirety simply because some people sometimes do some things we disapprove of is simply irrational. How about if we applied that thinking to other things - the internet being the prime example. We all know the horrific things that go on on the web and yet here we all are posting away merrily. Should we ban the internet because some people misuse it? Would we not be biting our nose off to spite our face? Same with music. There is no unambiguous directive against music in Islam, whatever the extremists would like us to believe and until someone can prove to me otherwise I'll continue with my love of music and the joys and rewards it brings me.
