I am not a servant of the ronda, although I can certainly read the floor. The milonga dancer is NOT a customer, its just another dance partner, instead!
As a DJ, I make a (personal) offer, just like I always did as a leader. I offer the best tangos I have collected through my tango life!
Also, this thread always philosophizes about THE optimal DJ. But this approach is completely wrong. As long as there are still many tango DJs among us, we have to assume that "DJ" is a corporate entity. We all complement each other, the optimal tango DJ manifests itself in the totality of us all, not just in a single successful or unsuccessful set. Like many things in the world, tango DJing should also follow the statistical characteristics of a normal distribution. And if you, Dear dancer, don't like my playlist, then go dancing tomorrow when a colleague offers a different extract.
