After 4 or 5 faster song you need to add a slower song. People can't dance all night if they don't get a slower song to rest up. You can just announce were going to slow it down a little to let people rest and grab a drink. They always seemed to understand when we did it.

Your not just playing, your controlling the crowd and if your playing at a bar they want to sell drinks, so slowing it down will get some off the dance floor so they have time to drink something. That will make your employer happy.

We had bar owners tell us to take longer breaks and slow it down, everyone is on the floor and were not selling any drinks.
