As a fellow DJ I empathise with Kaptin and the points he is making. I often give this expalnation: For every song you have heard in your life, at some point you had never heard that song. You make the choice if you like it or not.

The Dj's job is to entertain but also to play something you never heard before in the hope you like it. There is no greater pleasure than an excited individual asking what a new song is called. We know that you want to dance, we know you want to have a good time, we know that you want to hear stuff you know, but cut us some slack and let us get on with it.. If you ask us to play something unsuitable, (would you ask for northern soul in a techno club) it isn't gonna happen and it is the haranguing of the DJ that causes the bad vibe. Open your ears and open your mind, you might find that there's more to life than Lady(boy) GaGa, and if you don't like what you hear then go somewhere else and leave the people who do like it in peace.
