Virtual DJ lead the pack again with their powerful sound mixing software allowing people to enjoy music like never before. There used to be a time when parties used to be expensive and quite a hassle with all the equipment needed set-up just for decent music to be played. Virtual DJ allows one a complete dj setup with a pc and a decent sound system, but it can be a challenge to use(DJ experience may be necessary or familiarity with sound mixing equipment/terminology)
It can be hooked up to USB sound mixing equipment which offered the best results but hard work and perseverance may get you decent sound mixing all with your mouse and pc.
