Bernie,

I've played a lot of Christmas In July jobs, mainly for sales at upscale jewelry stores. They want Christmas music about 50 percent of the time, and your usual routine the other 50 percent of the time. Keep in mind the main reason they hired you is to provide entertainment for the customers and get them into a certain mood - which in this case is gift purchases. So, most of the Christmas songs should traditional, and upbeat.

Good Luck,

Gary
