To add to the already very valid points in this thread, I feel a good dj needs the ability to take many factors into consideration and make good choices based on these. Factors such as the venue, slot time, crowd reaction, track selection, when to change to mood etc.
A high level of technical ability and smooth well executed mixing is also required, which I feel is somewhat lacking nowadays. As a dj myself one of my pet hates is guys who's ego clearly outweighs their talent, i feel theres far to many of these people gigging regurlarly which is bringing the whole scene down, unfortunately its more about the ability to bring mates/buses than the music......which makes me sad
