I agree with FXDif.  You've only got to listen to the dance music charts on local radio to realise it's going down the toilet.  DJs in my opinion have NO talent.  I have dejayed myself and admittedly it was difficult at first but no harder than trying to ride a bike for the first time.  I am also a record producer and I feel there is so much more skill involved in composing a record that lifts peoples emotions and makes them feel good.  If you have worked in a studio there are so many parameters on all the equipment it is almost impossible to master.
Why do people insist on saying 'I'm going to see DJ Dave tonight'.  He is only as good as his records and where did they come from?  DJing in my opinion has very limited skill and this can be easily simulated on a computer.  Just look at programs like Traktor DJ Mixer.  Where's the skill involved now.  All it does is take a playlist, beat matches all the records and mixes them together AUTOMATICALLY.  Where's the skill now?  Show me a program that has AUTOMATICALLY created a top ten hit or a club anthem.  No, it's taken long hours in a recording studio by talented musicians, not by a turntable operator who knows how to control a fader and pitch controller (2 parameters).
If music is maturing why is the music industry constantly releasing old remixed tunes and old skool albums.  The dance music industry IS evolving - for the financial benefit of DJs and their record companies, not the clubbers who line the DJs pockets.
