Marketplace.org: Music On Hold With Easy On Hold®
"As Tim Brown of Easy On Hold points out, that gets pretty complicated, pretty fast. "In the United States, we have three different providers of these licenses. If you're sure if you're just playing a song licensed by BMI, then you can just pay BMI. But if you're playing a variety of songs, there's no way for you to really be able to track all that. It gets to be a hassle. Which is why most businesses just find it easier to go through a company like his, which offer licenses via businesses that churn out music composed specifically for this purpose."
