I guess its not really different than traditional DJing when you play one track after another....only the Beat matching has been removed which also removes one skill element, albeit a major skill of the DJ.
Whats left then? the ability to make remixes, crafty transitions (EFX) and intelligent track selection (something that is also somewhat lacking from a lot of DJs these days).
The positive element is that a producer can play his own stuff out that night rather than have to get it pressed onto vinyl. Although the CDJ has become common in clubs now for that purpose too.
I dunno?? I am going around in circles in my head now....PLAY IT DONT FAKE IT!! nuff..
