Just to give you a warning so that you know what you may run into down the road....
All music is copywrited. There are several groups that devote a lot of time and money tracking down people that are using music in a business environment without paying liscensing fees. The two big ones are BMI and ASCAP. If you use a radio, a cd player, or downloaded music as an MOH source without paying the fees, you can be sued.
