If you find yourself with 3 minutes between every song then you need to start digging in a little deeper. I have ADD in the DJ booth, and only in the DJ booth, and can't sit still and just let songs play out.
I'll dance, drink, makeout with my girlfriend, make fun of the bad dancers with my DJ buddies... and keep looking for that next track. There's too much to do now to have 3 minutes to just stand around.
