When my husband was stationed in Korea, long time ago, he used to work at a club and he was a DJ. No wonder he knows a lot of songs. He said that versatile dj mixers was his best friend. It makes the music sound sensational and we do know that when the music is great, people are encouraged to dance and they enjoy it a lot. That is when they come back and that means more business. In clubs, lame music and bad DJ results in less customers. People love to enjoy after working hard all day, and they need great music to relax and have fun all night.
