===========
Very much a first Baz Also agree with you, throw in a few unknowns, if you've got the dance-floor people will carry on dancing. But the problem could be, yes the DJ has the floor, yes he/she's thrown in a few unknowns, yes the people have danced, and he/she thinks, I'll throw in a few more, all of a sudden you've got a dis-satisfied crowd.
Then IMO, no matter how good the DJ is, he/she may have problems getting the crowd back into a dancing mood.
