Scenario at a lot of venues is DJ comes on plays a couple of unknown/semi known tunes & empties the floor - he then sticks on Moses Smith/Rufus Lumley etc. & fills the floor - so it all goes round in circles again.
The people who go to a lot of gigs don't want to listen to anything new to their ears - they are too busy going to dance classes, flash mobbing or attending venues in shopping centres !!
