Truthfully, picking what song goes next feels like a job well suited for an AI, or even just a basic recommendation system based on up and down votes.
Of course there's a real time component to DJing as well. Paying attention to the crowd and how they're reacting to your mix. That's the magic that's harder to automate.
I'd like to see it. As someone who's DJ'd a fair amount for large crowds (1000+) my value always seemed to be in choosing tracks that lit up the audience and made the set progress to a satisfying peak.
The technical aspects were always not that important.
