I am always amazed when a story like this comes out and people defend the DJ in question, saying it's the music that matters etc etc. You paid your $$$ to see him DJ live, and he's stood there fobbing you off miming to a mix CD... Not good! I think it's disrespectful to the fans, and it says a lot about the DJ/artist too. If you've got so little respect for your fans and the people who enjoy (and buy!) your music that you would pretend to DJ and make fools of them, then that's a pretty sad state of affairs.
