They are all local locations (within 50 miles). They just want a music source where they control the content as far as what is playing. Their current setup besides being not legal allows the workers to jack in their phones and play whatever (which is usually content they aren't in agreement with).

Thanks to everyone for the replies
One thing I have learned in this industry. It is easier to pull a wire than it is to push one.
