My favorite feature of MusicMaster has to be the Rule Tree Wizard which helps you find those things you may have "hurried" over when setting things up. I am a big fan of double checking and MusicMaster seems to do that for you... awesome feature. We chose MusicMaster because it plays with everyone. We can continue to use it no matter what software we run our "On Air" side with. It's just a versatile and easy to use program, well done.
