I would say your in trouble when those kids start requesting songs if you don't know or have them already,.......that said, I would suggest you go on some Top requested DJ song websites and look at some of their lists of songs for dancing to get an idea of what the average people at today affairs like then add to your selections....especially the popular line dances also like electric slide, cupid shuffle, cha cha slide, the Wobble dance, paradise by the dashboard lights, footloose, YMCA, twist, hot hot hot, etc,..good luck out there..
