Out of curiosity, where does the line of what "uses" is get drawn?
That determination as well as the cost depends on several factors. Whether or not the venue is a business and it's type, how the music is distributed and who's control is it under.
For instance, if a radio or CD player is located on a shelf in a restaurant kitchen for the kitchen help to listen to it would not be subject to royalty fees. It's considered to be under the control of the people in the kitchen for their enjoyment. However, a CD player connected to speakers in the dining areas would be subject because the music is for the enjoyment of the customers and enhances the business. Fees are based on the square footage and number of speakers.
So, you have nothing to worry about with your boombox on the job site.
