In other radio automation programs (I don’t say any name ;)) there is a option to hear what it sounds like when you set the “Start Next” point.
For example: when I set the point and I click preview, the same track starts at the “Start next” point. In this way you can simluate how it sounds and adjust the “Start next” point.
When you click “test” in MairList, you just hear the point when a next song should start. It is correct ofcourse, but maybe it’s good to “hear” what it will sound like.
