Most DJs play for dancing. But nowadays a growing trend is DJs for atmosphere; not just music from some anonymous source such as radio, internet, tape, etc, but a DJ playing music for talking. Sort of like replacing the electric fans to keep the air moving with specialized people to wave hand-fans.
There are some places with DJs playing atmosphere music in the Long Beach area. And this isn't "dinner music", much of what they play is dance music. Sad, IMO of course, that we've come from dance music for dancing, to dance music for spectating, to dance music for sitting on your butt. [One of these days I'll have to see if any academic discussions related to this sort of thing exist; like culture studies perhaps.]
